First Aid
First aid is the provision of initial care for an illness or injury. It is usually performed by a non-expert person to a sick or injured person until definitive medical treatment can be accessed. Certain self-limiting illnesses or minor injuries may not require further medical care past the first aid intervention. It generally consists of a series of simple and in some cases, potentially life-saving techniques that an individual can be trained to perform with minimal equipment.
While first aid can also be performed on all animals, the term generally refers to care of human patients.
Conditions that often require first aid
Also see medical emergency.
- Altitude sickness, which can begin in susceptible people at altitudes as low as 5,000 feet, can cause potentially fatal swelling of the brain or lungs.[8]
- Anaphylaxis, a life-threatening condition in which the airway can become constricted and the patient may go into shock. The reaction can be caused by a systemic allergic reaction to allergens such as insect bites or peanuts. Anaphylaxis is initially treated with injection of epinephrine.
- Battlefield first aid - This protocol refers to treating shrapnel, gunshot wounds, burns, bone fractures, etc. as seen either in the ‘traditional’ battlefield setting or in an area subject to damage by large scale weaponry, such as a bomb blast or other terrorist activity.
- Bone fracture, a break in a bone initially treated by stabilizing the fracture with a splint.
- Burns, which can result in damage to tissues and loss of body fluids through the burn site.
- Choking, blockage of the airway which can quickly result in death due to lack of oxygen if the patient’s trachea is not cleared, for example by the Heimlich Maneuver.
- Childbirth.
- Cramps in muscles due to lactic acid build up caused either by inadequate oxygenation of muscle or lack of water or salt.
- Diving disorders, drowning or asphyxiation.[9]
- Gender-specific conditions, such as dysmenorrhea and testicular torsion.
- Heart attack, or inadequate blood flow to the blood vessels supplying the heart muscle.
- Heat stroke, also known as sunstroke or hyperthermia, which tends to occur during heavy exercise in high humidity, or with inadequate water, though it may occur spontaneously in some chronically ill persons. Sunstroke, especially when the victim has been unconscious, often causes major damage to body systems such as brain, kidney, liver, gastric tract. Unconsciousness for more than two hours usually leads to permanent disability. Emergency treatment involves rapid cooling of the patient.
- Heat syncope, another stage in the same process as heat stroke, occurs under similar conditions as heat stroke and is not distinguished from the latter by some authorities.
- Heavy bleeding, treated by applying pressure (manually and later with a pressure bandage) to the wound site and elevating the limb if possible.
- Hyperglycemia (diabetic coma) and Hypoglycemia (insulin shock).
- Hypothermia, or Exposure, occurs when a person’s core body temperature falls below 33.7°C (92.6°F). First aid for a mildly hypothermic patient includes rewarming, but rewarming a severely hypothermic person could result in a fatal arrhythmia, an irregular heart rhythm.
- Insect and animal bites and stings.
- Joint dislocation.
- Poisoning, which can occur by injection, inhalation, absorption, or ingestion.
- Seizures, or a malfunction in the electrical activity in the brain. Three types of seizures include a grand mal (which usually features convulsions as well as temporary respiratory abnormalities, change in skin complexion, etc.) and petit mal (which usually features twitching, rapid blinking, and/or fidgeting as well as altered consciousness and temporary respiratory abnormalities).
- Muscle strains and Sprains, a temporary dislocation of a joint that immediately reduces automatically but may result in ligament damage.
- Stroke, a temporary loss of blood supply to the brain.
- Toothache, which can result in severe pain and loss of the tooth but is rarely life threatening, unless over time the infection spreads into the bone of the jaw and starts osteomyelitis.
- Wounds and bleeding, including lacerations, incisions and abrasions, Gastrointestinal bleeding, avulsions and Sucking chest wounds, treated with an occlusive dressing to let air out but not in.
Name | Description |
---|---|
avulsion | In an avulsion, a portion of skin is torn. This can be partial, with a portion of skin remaining as a "flap." In a total avulsion, a body part is completely torn off. |
bruise | Bleeding that occurs under the skin causes discoloration, swelling. The area begins as red but may turn into a "black and blue mark." |
cut | A cut is a split in the skin caused by a sharp object, such as a knife, or even a dull object. A cut can have either a jagged or smooth edge. |
puncture | A puncture wound is caused when the skin is pierced by a sharp object. Included in this category are gunshot wounds, impaled objects, and an object that passes totally through a part of the body. |
scrape | A scrape is very common, and occurs when skin is rubbed or scraped away. |
After a long day of being cooped up in a stuffy classroom listening to your teachers ramble on about the rise of the Communist party and the conjugations of the verb "estar," you decide that you're in the mood for a quick game of roller hockey with some equally stir-crazy friends. As you swoop in to fire a slap shot at the goal, the unthinkable happens: you hit a rock. And not just a pebble; this is a big, trip-you-up rock that you didn't see because your eyes were locked on that ball. So, before you know it, you've slid about five feet on your poor, unprotected knees. Your first thought is, "Did I make the shot?" Your second thought comes quickly with the hot sting as you look down and see the red streaks of blood appear where your skin once was. "OW!!!" What do you do?
- Stop the bleeding by applying pressure with a clean, absorbant cloth, or if cloth is unavailalble, your fingers.
- If the blood soaks through, apply a second bandage on top. Do not take off the first bandage because it will disturb the clotting that has already taken place.
- If bleeding still doesn't stop, raise the wound above heart level.
- Once bleeding stops, clean the wound gently with soap and water, or just water. It is very important to get all debris or dirt out.
- Apply an antibiotic ointment such as bacitration or a triple antibiotic ointment. Remember, some people are allergic to these ointments, so contact your doctor if you have any doubts.
- Wrap the wound firmly in a cloth or a bandage. Do not cut off circulation!
That Sunday remains the most vivid day in Cynthia's memory. She was cutting the bagels that John brought home, as she did every Sunday, when the knife slipped....The wash of bright, red blood was sudden and frightening. Thankfully, she and John knew exactly what to do.
- Covering the wound with a clean dressing, press against it firmly with your hand.
- Elevate the wound above the level of the heart.
- The clean dressing should then be covered over with a roll bandage (like an Ace) to hold the dressings in place.
- If bleeding still does not stop, add additional dressings over the roll bandage.
- Squeeze a pressure point, the artery against the bone. This is in the bottom upper arm, or where the leg bends at the hip.
- Once the bandages and pressure point are being maintained, have someone call EMS if they have not already.
When part of the body has been torn off...
- Try to find the part
- Wrap it in a clean dressing and place in a plasctic bag.
- Put the bag on ice, but don't freeze.
- Take the part to the hospital.
When an object is impaled in a wound...
- Do not remove it. You could reveal an open artery which would then be awfully hard to deal with, a.k.a. nearly impossible.
- Bandage many dressings around the object to immobilize it and support it in its position in the wound.
Splinters...
- A small splinter in the skin should be removed with tweezers.
- For a splinter in the eye, seek emergency help immediately, do not touch it.
Nosebleeds...
- Have the victim sit with his or her head tilted a little bit foward while pinching his or her nostrils together.
- One could also place an ice pack on the bridge of the nose.
Injury to the mouth...
- If the injury does not involve the head, neck, or spine, have the victim sit with the head slightly tilted foward. If the victim is unable to reach this position, place the victim on his or her side. This ensures that blood drains from the mouth.
- If the injury has broken the lip, place a clean rolled dressing between the lip and gum. Applying cold can also help.
If a tooth is knocked out...
- Place a small roll of sterile gauze in the gap left by the tooth that was knocked out.
- Pick up the tooth not by the root, but by the crown, the part you see when you smile in the mirror. If you can, place the tooth back how it belongs in the socket.
- If you can't put the tooth back in, put the tooth in a container with cool, fresh milk. If this cannot be done, use water.
If the bleeding is bright red, or spurts from the wound, CALL EMS.
If the wound is very deep or large, CALL EMS.
If the victim is in severe pain or you suspect serious damage, CALL EMS.
If you can't wash all the debris out of the wound, call your doctor immediately.
If you think you may need stitches (if the wound is in a place where you would want to minimize scarring) call your doctor immediately.
If you see any of the signs of a serious infection - redness, soreness, swelling, red streaks, weeping of pus, or redness that extends more than a finger width beyond a cut - call your doctor immediately.
Types of Burns
Superficial Burn (First Degree)
A first degree burn involves only the top layer of skin. The skin is red and dry and usually painful. The burned area may also swell. Most sunburns are superficial burns. This type of burn usually heals in 5-6 days without any permanent scarring.
Partial-Thickness Burn(Second Degree)
A second degree burn involves the top layers of skin. The skin is red with blisters that may open and weep clear fluid, giving the skin a wet appearance. The area may also appear mottled. The burn is usually painful and often swells. This type of burn usually heals in 3-4 weeks, and scarring may occur.
Full-Thickness Burn(Third Degree)
A third degree burn destroys all layers of skin and any or all of the underlying structures(fat, muscles, bones and nerves). The burn appears brown or black(charred) with the tissues underneath sometimes appearing white. This type of burn can be extremely painful or relatively painless if the burn destroys the nerve endings. This burn is critical and requires immediate medical attention.
Care for Burns
- Stop the burning. Put out flames or remove the victim from the source of the burn.
- Cool the burn. Use large amounts of cool water to cool the burn. Never use ice except on small superficial burns, because it causes body heat loss. If the area cannot be immersed, like the face, you can soak a clean cloth and apply it to the burn, being sure to continue adding water to keep the cloth cool.
- Cover the burn. Use dry, sterile dressings or a clean cloth to help prevent infection and reduce pain. Bandage loosely. Do not put any ointment on a burn unless it is very minor. Do not use any other home remedies, and do not break any blisters. For minor burns or burns with broken blisters that are not severe enough to require medical attention, wash the burned area with soap and water, keep it clean and apply an antibiotic ointment. Remember, some people can be allergic to topical ointments, so if you have any doubts, call your doctor for advice. For a victim of severe burns, lay him or her down unless he or she is having trouble breathing. Try to raise the burned areas above the level of the victim's heart if possible, and protect the victim from drafts.
Call EMS in any case of a chemical burn. Remove the chemical from the skin or eyes immediately by flushing the area with large amounts of cool running water until EMS arrives. Remove any clothes with chemicals on them, and be careful not to spread the chemical to other body parts or to yourself. Chemical burns can be caused by chemicals used in manufacturing or in a lab, or by household items such as bleach, garden sprays or paint removers.
Call EMS in any case of an electrical burn. Do not go near the victim unless you are sure the power source has been turned off. The burn itself will not be the major problem. If the victim is unconscious, check breathing and pulse. Check for other injuries, and do not move the victim because he or she may have spinal injuries. Cover an electrical burn with a dry, sterile dressing. Do not cool the burn. Prevent the victim from getting chilled. There may be two wounds, one where the current entered the body and one where it left, and they may be deep. Electrical burns can be caused by power lines, lightening, defective electrical equipment,and unprotected electrical outlets.
Burns caused by solar radiation may be painful and may also blister. Cool the burn. You may want to put a product designed specifically for sunburn on the area; these products usually contain aloe vera and help cool the area and reduce the pain. Protect the burn by staying out of the sun. If you must go in the sun, wear a sunscreen with an SPF of at least 15 and reapply it frequently. Be sure to cover up any existing sunburn if you are going to be outside again.
What did I do?
Your body consists of over 200 bones of all different shapes and sizes. All of these bones in addition to muscles and the tendons and ligaments that put them together form the skeleton, which serves to protect many of the organs your body uses to function normally. Bones are dense and very strong, and they tend not to break easily, except in elderly people who have developed osteoperosis, a gradual weakening of the bones. Bone injuries are often quite painfull, and they may bleed, as all bones have an ample amount of blood and nerves. The two types of bone injuries are fractures, which may be open or closed, and dislocations, which involve muscles and joints as well. The body has over 600 muscles, which are soft tissue. Injuries to the brain, the spinal cord or nerves can affect a person's muscle control, and when a muscle is injured, a nearby muscle may take over for the injured one. A joint is formed where the ends of two or more bones come together in one place. The bones are held together by ligaments, which tear when a joint is forced beyond its normal range of movement. A sprain is the tearing of ligaments at a joint. A strain is a stretching and/or tearing of muscles or tendons.
An open fracture occurs when an arm or a leg twists in such a way that the broken bone ends tear through the skin, causing an open wound. In a closed fracture the skin is not broken; this type of fracture is much more common than an open fracture. An open fracture brings with it a chance of infection and also severe bleeding. Fractures can be life-threatening if they sever an artery, affect breathing, or occur in very large bones such as the femur in the thigh. A motor vehicle accident or any fall from a height may cause a fracture.
A dislocation is typically more noticeable than a fracture. A dislocation occurs when a bone moves away from its normal position at a joint. A violent force tears the ligaments that hold the bone in place at a joint, and the joint will no longer function. Usually, the displaced bone causes an obviously abnormal bump, ridge or hollow.
Sprains may swell but typically heal quickly. Pain may be minimal and the victim may be active soon, in which case the joint won't heal properly and will remain weak. It is likely to be reinjured more severely, possibly involving a fracture or dislocation of the bones at the joint. The most easily injured joints are at the ankle, knee, wrist and fingers.
Strains are frequently caused by lifting a very heavy object or working a muscle too hard. They usually involve muscles in the neck, back, thigh or back of the lower leg. Strains tend to reoccur, especially those located in the neck or back.
An x ray is the best way to assess the extent of damage to a bone, muscle or joint. However, you may be able to judge how serious the injury is by its appearance. The area may be red, bruised, swollen, twisted, or have bumps, ridges or hollows. The area may be painful to touch as well as to move, or the victim may be unable to move it. If you compare an injured body part with an uninjured one, you may be able to locate any abnormalities; this works well with an arm, a leg, a shoulder, a knee...you get the idea. Sometimes the victim may have heard a snap, crackle or a pop when the injury occurred, or he or she may feel bones grating. Also, the victim's hands and fingers or feet and toes may tingle or feel numb. (Hey, you oxymorons...how can something feel numb?)
What do I do?
It does not matter whether the injury was to a bone, muscle or joint-you don't need to know specifically what the injury is in order to care for it! The formual for proper care is rest, ice and elevation. Make the victim as comfortable as possible, and apply ice to reduce pain and swelling. Minimize movement of the injured part by supporting it with something like a pillow.
Do not try to move a patient with a severely broken bone unless it is absoluely necessary. Calling EMS is the best couse of action in this case. However, if you must move the patient you must immobilize the injured body part. One way is to splint it, but do this only if it can be done without hurting the victim, and always attempt to splint the part in the position you found it. Splint the injured area and the joints above and below the injured area. You may use another body part, like an injured leg to an uninjured one, or an injured arm to a chest; this is called an anatomic splint. Make asoft splint from folded blankets or towels, or use a triangular bandage to make a sling, another type of soft splint, which is used to support an injured arm, wrist or hand. Use folded magazines and newspapers, cardboard or metal strips to support the injured body part with a rigid splint. Use several folded triangular bandages to secure the injured body part to the splinting material, tying them securely but not too tightly.Apply ice and raise the injured part, and prevent the victim from getting chilled or overheated. Remember to be reassuring!
- the victim has sustained injuries to the head, neck or back
- the victim is having trouble breathing
- the victim is unable to move or use the injured body part without experiencing pain
- the injury appears to be a severely broken bone.
If you think the victim may have a head or spine injury, DO NOT move him or her; leave the victim lying flat. EMS will be able to move and treat the patient without causing further injury to the victim.
Beware of signs that indicate head and spine injuries. These include:Choking Adult
changes in consciousness; vision and breathing problems; nausea and vomiting; inability to move a body part; steady headache; tingling or loss of sensation in hands, fingers, feet or toes; blood in the ears or nose; seizures, severe pain, pressure or bleeding in the head, neck or back; bruising of the head; and loss of balance
If you see these signs in a victim, call EMS immediately, and DO NOT attempt to move the victim or you may injure him or her further. Minimize movement of the head and spine, maintain an open airway(use a chin lift but NO head tilt unless you want to paralyze the victim!!!), check consciousness and breathing, control any bleeding, and prevent the victim from getting chilled or overheated.
Conscious Adult
If a person is clutching his or her throat with both hands, he or she is making the universal sign for choking. If the person can cough or talk, encourage him or her to continue coughing. Once the victim can no longer talk or cough, you must clear the obstructed airway. To clear the obstructed airway that causes choking, you must perform the Heimlich maneuver, also known as abdominal thrusts. Stand behind the conscious choking adult, wrapping your arms around his or her waist. With one hand, make a fist. Place the thumb side of the fist against the victim's abdomen just above the bellybutton. Be sure your hand is far below the tip of the breastbone. Put your other hand over the fist and give quick upward thrusts into the victim's abdomen. Continue giving thrusts until the object blocking the airway is dislodged and the victim begins to breathe, or until the victim becomes unconscious.
Unconscious Adult
If, during the primary survey, your breaths will not go in an unconscious adult, and you retilted the head and tried again but the breaths still would not go in, you must assume the victim's airway is obstructed.
If the victim is a conscious choking adult who became unconscious, you must lower him or her to the floor on his or her back. Perform a head tilt and chin lift to try to open the airway, and attempt to remove the obstruction by sweeping it out of the victim's mouth with your finger. This is called a finger sweep. Always use a hooking action, being careful not to lodge the object in further. Perform a head tilt and a chin lift and give 2 slow breaths. If the breaths still do not go in, go to abdominal thrusts.
Straddle one or both of the victim's thighs. Place the heel of one hand on the victim's abdomen, just above the bellybutton yet far below the tip of the breastbone. Place your other hand on top of the first, interlacing your fingers, and give 5 quick upward thrusts. Then do a finger sweep and give 2 slow breaths. If air still will not go in, continue giving 5 abdominal thrusts, a finger sweep and 2 slow breaths. Continue giving thrusts until the object is dislodged, air goes into the victim, or trained medical personnel takes over. If the victim is not breathing but has a pulse, you must perform Rescue Breathing. If the victim is not breathing and does not have a pulse, go to CPR.
Conscious Child
If the child can cough or talk, encourage him or her to continue coughing. If the child cannot cough or talk, ask if he or she is choking. Perform abdominal thrusts. Stand behind the victim, wrap your arms around his or her waist, and make a fist with one hand. Place the thumb side of the fist against the child's abdomen, above the bellybutton yet far below the tip of the breastbone. Put your other hand over the fist and give quick upward thrusts into the victim's abdomen. Continue giving thrusts until the airway is cleared and the child begins to breathe, or until the child becomes unconscious.
Unconscious Child
If the child was a conscious choking victim who became unconscious, lower the child down onto his or her back. Or, you may have determined during the primary survey that air would not go in, even after you retilted and tried again. You must give the child 5 abdominal thrusts, do a finger sweep if you see the object, and open the airway with a head tilt and a chin lift and give 2 slow breaths. If the breaths still will not go in, continue giving abdominal thrusts, a finger sweep and 2 slow breaths until the object is expelled, the child starts to breathe or cough, or EMS takes over. If the child is not breathing but has a pulse, you must perform Rescue Breathing. If the child is not breathing and does not have a pulse, go to CPR.
Conscious Infant
During the primary survey, you may determine that the infant is conscious and cannot breathe, cough or cry. You must give 5 back blows and 5 chest thrusts.
Place the infant faceup on your forearm. Put your other arm on top of the infant. Use your thumb and fingers to hold the infant's jaw, sandwiching the infant between your forearms. Turn the infant over, facedown on your forearm. Place your arm down on your thigh, being sure that the infant's head is lower than his or her chest. Using the heel of your hand, give 5back blows between the infant's shoulder blades. Be sure to hold the infant's jaw with your thumb and fingers to stabilize his or her head.
You must turn the infant back over to give chest thrusts. Place your free hand and forearm across the infant, sandwiching it between your forearms and supporting his or her head . Turn the infant over onto his or her back and place your arm down on your thigh, making sure the infant's head is lower than his or her chest. Imagine a line across the infant's chest between the nipples. Place your ring finger on the infant's breastbone just below the imaginary line. Place the pads of the next two fingers just under the line. Raise your ring finger, and if you can feel the notch at the tip of the infant's breastbone, move your fingers up a little bit. Compress the infant's breastbone 1/2-1 inch with the pads of your fingers and then let the breastbone return to its normal position. Give 5 compressions. Continue giving back blows and chest thrusts until the infant can breathe or cough, or until the infant becomes unconscious.
Unconscious Infant
If the infant was a conscious choking victim who became unconscious, place the infant down on its back. Or, you may have determined during the primary survey, even after retilting the head and trying again, that air would not go in. Perform5 back blows and then 5 chest thrusts. Do a foreign body check: open the infant's mouth, holding the tongue and lower jaw and lifting them upward, and look for an object; if you do see an object, do a finger sweep to remove it with your little finger. Then give 2 slow breaths. If air still will not go in, continue doing back blows, chest thrusts, foreign body check and2 slow breaths until the infant starts to breathe or cough or air goes in. If the infant is not breathing but has a pulse, you must perform Rescue Breathing. If the infant is not breathing and does not have a pulse, go to CPR.
A poison is a substance that causes injury or illness when it gets into a person's body.The four ways a person can be poisoned are: ingestion(swallowing it), inhalation (breathing it), absorption (absorbing it through the skin), and injection (by having it injected into the body). Ingested poisons include foods, alcohol, medication, household and garden items, and certain plants. Inhaled poisons may be gases, like carbon monoxide from car exhaust, carbon dioxide from sewers, and chlorine from a pool, or fumes from household products like glue, paint, cleaners, or drugs. Absorbed poisons enter the body through the skin; they may come from plants, fertilizers or pesticides. Injected poisons enter the body through bites or stings of insects, spiders, ticks, marine life, snakes, and other animals, or medications injected with a hypodermic needle.Conscious AdultIf a choking conscious adult is noticeably pregnant or too obese for you to wrap your arms around in order to perform abdominal thrusts, you must give chest thrusts instead. Stand behind the victim, placing your arms under the victim's armpits and around his or her chest. Make a fist with one hand and put the thumb side of the fist against the center of the victim's breastbone. Make sure your thumb is on the breastbone, not the ribs, and that you are not near the tip of the breastbone. Put your other hand over the fist and give quick inward thrusts. Continue giving thrusts until the object is dislodged, or until the victim becomes unconscious.Unconscious AdultIf the victim was a conscious choking pregnant woman or obese person who became unconscious, lower the victim gently onto his or her back on the floor. Or, you may have determined during the primary survey, even after retilting the head and trying again, that air woiuld not go into your pregnant or obese victim. You must give chest thrusts. Kneel beside the victim, placing one hand on the center of the victim's breastbone and then placing your other hand on top of it. Give 5 quick thrusts, compressing the chest 1 1/2-2 inches. Do a finger sweep, open the airway with a head tilt and a chin lift, and give 2slow breaths. If air still will not go in, continue giving chest thrusts, finger sweeps and 2 slow breaths until the object is expelled and air goes in. If the victim is not breathing and has a pulse, go to Rescue Breathing. If the victim is not breathing and does not have a pulse, go to CPR.
Ingestion
If you suspect that someone has been poisoned, call your Poison Control Center or EMS immediately. Signs of poisoning are: nausea, vomiting, diarrhea, chest or abdominal pain, difficulty breathing, changes in consciousness, seizures, or burns around the lips or tongue or on the skin. If you believe someone may have swallowed a poison, try to determine what type of poison was ingested, how much was taken, and when it was taken. If you find a container, bring it to the telephone with you when you make your emergency call. Do not give the victim anything to eat or drink unless medical professionals tell you to. If you are unsure of what the poison was and the victim vomits, savce some of ti so that the hospital may analyze it and determine what the poison was.
Inhalation
If you suspect that someone has been poisoned, call your Poison Control Center or EMS immediately. Signs of poisoning by inhalation may include pale or bluish skin. Remove the victim from the source of the toxic fumes so he or she can get some fresh air as soon as possible.
Absorption
If you suspect that someone has been poisoned, call your Poison Control Center or EMS immediately. If poison, such as dry or wet chemicals, gets on the skin, flush the area with large amounts of water, and continue flushing the area with water until EMS arrives. If you have simply had a run-in with poison ivy, poison oak or poison sumac, there is no need to call EMS. Wash the affected area with soap and water. If you develop a rash, put a paste of baking soda and water on the area several times a day, or use an anti-itch lotion or an antihistamine to relieve the itchiness. Be aware that some people can have allergic reactions to even over-the-counter drugs to stop itching...use caution and if you have any doubts about whether you are allergic, talk to you doctor! . See a doctor if the condition gets worse, affecting large areas of the body or face.
Injection-Stings and Bites
If someone is stung by an insect, such as a bee, remove the stinger by scraping it away from the skin with your fingernail or a plastic card, or use tweezers. Wash the area with soap and water, cover it to keep it clean, and apply ice to reduce pain and swelling. If the victim begins to have trouble breathing, he or she may be experiencing an allergic reaction and his or her body is going into anaphylactic shock. You must CALL EMS immediately or the victim's airway may constrict, preventing breathing and killing the victim.
Scorpions and Spiders
Only a few species of scorpions are known to cause death. Scorpions live in dry regions of the southwestern U.S. and Mexico, under rocks, logs and the bark of certain trees. They are most active at night. If you are stung by ascorpion, you would be wise to call EMS unless you are positive that the one that bit you is not poisonous.
Only two spiders in the U.S. have bites that can make you seriously ill or kill you. The black widow spider is black with a reddish hourglass shape on the underside of its body. The brown recluse spider is light brown with a darker brown, violin-shaped marking on the top of its body. Both prefer dark, out-of-the-way places, and bites usually occur on the arms or hands of people rummaging in dark garages or attics or in wood piles(In other words, don't go looking for them and they won't bite you!).
Symptoms of spider bites and scorpion stings are: nausea, vomiting, difficulty breathing or swallowing, sweating and salivating profusely, severe pain in the bite/sting area, a mark indicating a bite/sting, and swelling of the area. If you suspect you have been bitten by a black widow or a brown recluse or stung by a scorpion, wash the wound, apply ice to the area, and call EMS immediately. Antivenins, medications that block the effect of the poison, are available.
Marine Life , Snakes and Other Animals
The stings of some different types of marine life, such as sting rays, sea anemones and jellyfish may make you sick. If you are stung, soak the affected area in salt water and apply a paste of baking soda or meat tenderizer, or even ice, as soon as possible to reduce swelling. If you are unsure what stung you, have a history of allergic reactions to marine life stings, are stung on the face or neck, or are having difficulty breathing, call EMS immediately.
Only four kinds of snakes found in the U.S. are poisonous: rattlesnake(distinctive rattling sound before it strikes), water moccasin, copperhead, and coral snake(distinctive red, yellow and black markings). If you are bitten by a snake, call EMS immediately. Wash the wound and immobilize the area, keping it lower than the heart if possible. DO NOT apply ice, DO NOT cut the wound, and DO NOT apply a tourniquet. Get yourself medical attention quickly.
If you are bitten by awild or domestic animal, you may get an infection and you will have injury to the soft tissue. The most serious possible consequence is rabies, which is transmitted through the saliva of diseased animals, including dogs, cats, raccoons, skunks, cattle, and bats. Infected animals may behave strangely; for example, a nocturnal animal like a raccoon may be active during the day, or the animal may drool, appear partially paralyzed, or act irritable, mean, or quiet. Rabies is fatal if it is not treated promptly. If you suspect that you have bitten by a rabid animal, call EMS immediately. Get away from the animal. DO NOT try to catch or hold it. Wash the wound with soap and water if it is minor, control bleeding and apply an antibiotic ointment and a dressing. If the wound is bleeding heavily, do not try to wash it; just try to control the bleeding, and call EMS. Try to remember what the animal looked like, as well as where you last saw it. Call EMS and inform them, and they will get the proper authorities involved.

The complete rules are extensive. But simply, play proceeds as follows: A player on one of the teams begins a 'rally' by serving the ball (tossing or releasing it and then hitting it with a hand or arm), from behind the back boundary line of the court, over the net, and into the receiving team's court. The receiving team must not let the ball be grounded within their court. They may touch the ball as many as three times. Typically, the first two touches are to set up for an attack, an attempt to direct the ball back over the net in such a way that the serving team is unable to prevent it from being grounded in their court.Volleyball is an Olympic team sport in which two teams of six players are separated by a net. Each team tries to score points by grounding a ball on the other team's court under organized rules.[1]
The rally continues, with each team allowed as many as three consecutive touches, until either (1): a team makes a kill, grounding the ball on the opponent's court and winning the rally; or (2): a team commits a fault and loses the rally. The team that wins the rally is awarded a point, and serves the ball to start the next rally. A few of the most common faults include:
- causing the ball to touch the ground outside the opponents' court or without first passing over the net;
- catching and throwing the ball;
- double hit: two consecutive contacts with the ball made by the same player;
- four consecutive contacts with the ball made by the same team.
- net foul: touching the net during play.
The ball is usually played with the hands or arms, but players can legally strike or push (short contact) the ball with any part of the body.
A number of consistent techniques have evolved in volleyball, including spiking andblocking (because these plays are made above the top of the net the vertical jump is an athletic skill emphasized in the sport) as well aspassing, setting, and specialized player positions and offensive and defensive structures.
History
Origin of volleyball
On February 9, 1895, in Holyoke, Massachusetts (USA), William G. Morgan, a YMCA physical education director, created a new game called Mintonette as a pastime to be played preferably indoors and by any number of players. The game took some of its characteristics from tennis and handball. Another indoor sport, basketball, was catching on in the area, having been invented just ten miles (sixteen kilometers) away in the city of Springfield, Massachusetts, only four years before. Mintonette was designed to be an indoor sport less rough than basketball for older members of the YMCA, while still requiring a bit of athletic effort.
The first rules, written down by William G Morgan, called for a net 6 ft 6 in (1.98 m) high, a 25×50 ft (7.6×15.2 m) court, and any number of players. A match was composed of nine innings with three serves for each team in each inning, and no limit to the number of ball contacts for each team before sending the ball to the opponents’ court. In case of a serving error, a second try was allowed. Hitting the ball into the net was considered a foul (with loss of the point or a side-out)—except in the case of the first-try serve.
After an observer, Alfred Halstead, noticed the volleying nature of the game at its first exhibition match in 1896, played at the International YMCA Training School (now called Springfield College), the game quickly became known as volleyball (it was originally spelled as two words: "volley ball"). Volleyball rules were slightly modified by the International YMCA Training School and the game spread around the country to various YMCAs.[2][3]
Refinements and later developments
The first official ball used in volleyball is disputed; some sources say that Spalding created the first official ball in 1896, while others claim it was created in 1900.[4][5][6] The rules evolved over time: in the Philippines by 1916, the skill and power of the set and spike had been introduced, and four years later a "three hits" rule and a rule against hitting from the back row were established. In 1917, the game was changed from 21 to 15 points. In 1919, about 16,000 volleyballs were distributed by the American Expeditionary Forces to their troops andallies, which sparked the growth of volleyball in new countries.[4]
The first country outside the United States to adopt volleyball was Canada in 1900.[4] An international federation, the Fédération Internationale de Volleyball (FIVB), was founded in 1947, and the first World Championships were held in 1949 for men and 1952 for women.[7] The sport is now popular in Brazil, in Europe (where especially Italy, the Netherlands, and countries from Eastern Europe have been major forces since the late 1980s), in Russia, and in other countries including China and the rest of Asia, as well as in the United States.[2][3][7]
Beach volleyball, a variation of the game played on sand and with only two players per team, became a FIVB-endorsed variation in 1987 and was added to the Olympic program at the 1996 Summer Olympics.[4][7] Volleyball is also a sport at the Paralympics managed by theWorld Organization Volleyball for Disabled.
Volleyball in the Olympics
Main article: Volleyball at the Summer Olympics
The history of Olympic volleyball traces back to the 1924 Summer Olympics in Paris, where volleyball was played as part of an American sports demonstration event.[8] After the foundation of FIVB and some continental confederations, it began to be considered for official inclusion. In 1957, a special tournament was held at the 53rd IOC session in Sofia, Bulgaria to support such request. The competition was a success, and the sport was officially included in the program for the 1964 Summer Olympics.[4]
The Olympic volleyball tournament was originally a simple competition: all teams played against each other team and then were ranked by wins, set average, and point average. One disadvantage of this round-robin system is that medal winners could be determined before the end of the games, making the audience lose interest in the outcome of the remaining matches. To cope with this situation, the competition was split into two phases with the addition of a "final round" elimination tournament consisting of quarterfinals, semifinals, and finals matches in 1972. The number of teams involved in the Olympic tournament has grown steadily since 1964. Since 1996, both men's and women's events count twelve participant nations. Each of the five continental volleyball confederations has at least one affiliated national federation involved in the Olympic Games.
The U.S.S.R. won men's gold in both 1964 and 1968. After taking bronze in 1964 and silver in 1968, Japan finally won the gold for men's volleyball in 1972. Women's gold went to Japan in 1964 and again in 1976. That year, the introduction of a new offensive skill, the backrow attack, allowed Poland to win the men's competition over the Soviets in a very tight five-set match. Since the strongest teams in men's volleyball at the time belonged to the Eastern Bloc, the American-led boycott of the 1980 Summer Olympics did not have as great an effect on these events as it had on the women's. The U.S.S.R. collected their third Olympic Gold Medal in men's volleyball with a 3-1 victory over Bulgaria (the Soviet women won that year as well, their third gold as well). With the U.S.S.R. boycotting the 1984 Olympic Games in Los Angeles, the U.S. was able to sweep Brazil in the finals to win the men's gold medal. Italy won its first medal (bronze in the men's competition) in 1984, foreshadowing a rise in prominence for their volleyball teams.
At the 1988 Games, Karch Kiraly and Steve Timmons led the U.S. men's team to a second straight gold medal. In 1992, underrated Brazil upset favourites C.I.S., Netherlands, and Italy in the men's competition for the country's first volleyball Olympic gold medal. Runner-up Netherlands, men's silver medalist in 1992, came back under team leaders Ron Zwerver and Olof van der Meulen in the 1996 Games for a five-set win over Italy. A men's bronze medalist in 1996, Serbia and Montenegro (playing in 1996 and 2000 as the Federal Republic of Yugoslavia) beat Russia in the gold medal match in 2000, winning their first gold medal ever. In 2004, Brazil won its second men's volleyball gold medal beating Italy in the finals. In the 2008 Games, the USA beat Brazil in the men's volleyball final.

Rules of the game
The court
The game is played on a volleyball court 18 meters (59 feet) long and 9 meters (29.5 feet) wide, divided into two 9 m × 9 m halves by a one-meter (40-inch) wide net placed so that the top of the net is 2.43 meters (7 feet 11 5/8 inches) above the center of the court for men's competition, and 2.24 meters (7 feet 4 1/8 inches) for women's competition (these heights are varied for veterans and junior competitions).
There is a line 3 meters from and parallel to the net in each team court which is considered the "attack line". This "3 meter" (or 10 foot) line divides the court into "back row" and "front row" areas (also back court and front court). These are in turn divided into 3 areas each: these are numbered as follows, starting from area "1", which is the position of the serving player:
After a team gains the serve (also known as siding out), its members must rotate in a clockwise direction, with the player previously in area "2" moving to area "1" and so on, with the player from area "1" moving to area "6".
The team courts are surrounded by an area called the free zone which is a minimum of 3 meters wide and which the players may enter and play within after the service of the ball.[9] All lines denoting the boundaries of the team court and the attack zone are drawn or painted within the dimensions of the area and are therefore a part of the court or zone. If a ball comes in contact with the line, the ball is considered to be "in". An antenna is placed on each side of the net perpendicular to the sideline and is a vertical extension of the side boundary of the court. A ball passing over the net must pass completely between the antennae (or their theoretical extensions to the ceiling) without contacting them.
The ball
Main article: Volleyball (ball)
FIVB regulations state that the ball must be spherical, made of leather or synthetic leather, have a circumference of 65–67 cm, a weight of 260–280 g and an inside pressure of 0.30–0.325 kg/cm2.[10] Other governing bodies have similar regulations.
Game play
Each team consists of six players. To get play started, a team is chosen to serve by coin toss. A player from the serving team throws the ball into the air and attempts to hit the ball so it passes over the net on a course such that it will land in the opposing team's court (theserve). The opposing team must use a combination of no more than three contacts with the volleyball to return the ball to the opponent's side of the net. These contacts usually consist first of the bump or pass so that the ball's trajectory is aimed towards the player designated as the setter; second of the set (usually an over-hand pass using wrists to push finger-tips at the ball) by the setter so that the ball's trajectory is aimed towards a spot where one of the players designated as an attacker can hit it, and third by the attacker whospikes (jumping, raising one arm above the head and hitting the ball so it will move quickly down to the ground on the opponent's court) to return the ball over the net. The team with possession of the ball that is trying to attack the ball as described is said to be on offense.
The team on defense attempts to prevent the attacker from directing the ball into their court: players at the net jump and reach above the top (and if possible, across the plane) of the net in order to block the attacked ball. If the ball is hit around, above, or through the block, the defensive players arranged in the rest of the court attempt to control the ball with a dig (usually a fore-arm pass of a hard-driven ball). After a successful dig, the team transitions to offense.
The game continues in this manner, rallying back and forth, until the ball touches the court within the boundaries or until an error is made. The most frequent errors that are made are either to fail to return the ball over the net within the allowed three touches, or to cause the ball to land outside the court. A ball is "in" if any part of it touches a sideline or end-line, and a strong spike may compress the ball enough when it lands that a ball which at first appears to be going out may actually be in. Players may travel well outside the court to play a ball that has gone over a sideline or end-line in the air.
Other common errors include a player touching the ball twice in succession, a player "catching" the ball, a player touching the net while attempting to play the ball, or a player penetrating under the net into the opponent's court. There are a large number of other errors specified in the rules, although most of them are infrequent occurrences. These errors include back-row or libero players spiking the ball or blocking (back-row players may spike the ball if they jump from behind the attack line), players not being in the correct position when the ball is served, attacking the serve in the front court and above the height of the net, using another player as a source of support to reach the ball, stepping over the back boundary line when serving, taking more than 8 seconds to serve,[11] or playing the ball when it is above the opponent's court.
Scoring
When the ball contacts the floor within the court boundaries or an error is made, the team that did not make the error is awarded a point, whether they served the ball or not. If the ball hits the line, the ball is counted as in. The team that won the point serves for the next point. If the team that won the point served in the previous point, the same player serves again. If the team that won the point did not serve the previous point, the players of the team rotate their position on the court in a clockwise manner. The game continues, with the first team to score 25 points (and be two points ahead) awarded the set. Matches are best-of-five sets and the fifth set (if necessary) is usually played to 15 points. (Scoring differs between leagues, tournaments, and levels; high schools sometimes play best-of-three to 25; in the NCAAgames are played best-of-five to 25 as of the 2008 season.)[12]
Before 1999, points could be scored only when a team had the serve (side-out scoring) and all sets went up to only 15 points. The FIVB changed the rules in 1999 (with the changes being compulsory in 2000) to use the current scoring system (formerly known as rally point system), primarily to make the length of the match more predictable and to make the game more spectator- and television-friendly.
Libero
In 1998 the libero player was introduced internationally.[13] The libero is a player specialized in defensive skills: the libero must wear a contrasting jersey color from his or her teammates and cannot block or attack the ball when it is entirely above net height. When the ball is not in play, the libero can replace any back-row player, without prior notice to the officials. This replacement does not count against the substitution limit each team is allowed per set, although the libero may be replaced only by the player whom they replaced.
The libero may function as a setter only under certain restrictions. If she/he makes an overhand set, she/he must be standing behind (and not stepping on) the 3-meter line; otherwise, the ball cannot be attacked above the net in front of the 3-meter line. An underhand pass is allowed from any part of the court.
The libero is, generally, the most skilled defensive player on the team. There is also a libero tracking sheet, where the referees or officiating team must keep track of who the libero subs in and out for. There may only be one libero per set (game), although there may be a different libero in the beginning of any new set (game).
Furthermore, a libero is not allowed to serve, according to international rules, with the exception of the NCAA women's volleyball games, where a 2004 rule change allows the libero to serve, but only in a specific rotation. That is, the libero can only serve for one person, not for all of the people for whom he or she goes in. That rule change was also applied to high school and junior high play soon after.
Recent rule changes
Other rule changes enacted in 2000 include allowing serves in which the ball touches the net, as long as it goes over the net into the opponents' court. Also, the service area was expanded to allow players to serve from anywhere behind the end line but still within the theoretical extension of the sidelines. Other changes were made to lighten up calls on faults for carries and double-touches, such as allowing multiple contacts by a single player ("double-hits") on a team's first contact provided that they are a part of a single play on the ball.
In 2008, the NCAA changed the minimum number of points needed to win any of the first four sets from 30 to 25 for women's volleyball (men's volleyball remained at 30.) If a fifth (deciding) set is reached, the minimum required score remains at 15. In addition, the word "game" is now referred to as "set".[12]
Changes in rules have been studied and announced by FIVB in recent years, and they have released the updated rules in 2009.[14]
Skills
Competitive teams master six basic skills: serve, pass, set, attack, block and dig. Each of these skills comprises a number of specific techniques that have been introduced over the years and are now considered standard practice in high-level volleyball.
Serve
A player stands behind the inline and serves the ball, in an attempt to drive it into the opponent's court. His or her main objective is to make it land inside the court; it is also desirable to set the ball's direction, speed and acceleration so that it becomes difficult for the receiver to handle it properly. A serve is called an "ace" when the ball lands directly onto the court or travels outside the court after being touched by an opponent.
In contemporary volleyball, many types of serves are employed:
- Underhand: a serve in which the player strikes the ball below the waist instead of tossing it up and striking it with an overhand throwing motion. Underhand serves are considered very easy to receive and are rarely employed in high-level competitions.
- Sky Ball Serve: a specific type of underhand serve occasionally used in beach volleyball, where the ball is hit so high it comes down almost in a straight line. This serve was invented and employed almost exclusively by the Brazilian team in the early 1980s and is now considered outdated. In Brazil, this serve is called Jornada nas Estrelas (Star Trek).
- Topspin: an overhand serve where the player tosses the ball high and hits it with a wrist span, giving it topspin which causes it to drop faster than it would otherwise and helps maintain a straight flight path. Topspin serves are generally hit hard and aimed at a specific returner or part of the court. Standing topspin serves are rarely used above the high school level of play.
- Float: an overhand serve where the ball is hit with no spin so that its path becomes unpredictable, akin to a knuckleball in baseball.
- Jump Serve: an overhand serve where the ball is first tossed high in the air, then the player makes a timed approach and jumps to make contact with the ball, hitting it with much pace and topspin. This is the most popular serve amongst college and professional teams.
- Jump Float: an overhand serve where the ball is tossed high enough that the player may jump before hitting it similarly to a standing float serve. The ball is tossed lower than a topspin jump serve, but contact is still made while in the air. This serve is becoming more popular amongst college and professional players because it has a certain unpredictability in its flight pattern.
Set
The set is usually the second contact that a team makes with the ball. The main goal of setting is to put the ball in the air in such a way that it can be driven by an attack into the opponent's court. The setter coordinates the offensive movements of a team, and is the player who ultimately decides which player will actually attack the ball.
As with passing, one may distinguish between an overhand and a bump set. Since the former allows for more control over the speed and direction of the ball, the bump is used only when the ball is so low it cannot be properly handled with fingertips, or in beach volleyball where rules regulating overhand setting are more stringent. In the case of a set, one also speaks of a front or back set, meaning whether the ball is passed in the direction the setter is facing or behind the setter. There is also a jump set that is used when the ball is too close to the net. In this case the setter usually jumps off his or her right foot straight up to avoid going into the net. The setter usually stands about ⅔ of the way from the left to the right of the net and faces the left (the larger portion of net that he or she can see).
Sometimes a setter refrains from raising the ball for a teammate to perform an attack and tries to play it directly onto the opponent's court. This movement is called a "dump".[15] The most common dumps are to 'throw' the ball behind the setter or in front of the setter to zones 2 and 4. More experienced setters toss the ball into the deep corners or spike the ball on the second hit.
Pass
Also called reception, the pass is the attempt by a team to properly handle the opponent's serve, or any form of attack. Proper handling includes not only preventing the ball from touching the court, but also making it reach the position where the setter is standing quickly and precisely.
The skill of passing involves fundamentally two specific techniques: underarm pass, or bump, where the ball touches the inside part of the joined forearms or platform, at waist line; and overhand pass, where it is handled with the fingertips, like a set, above the head. Either are acceptable in professional and beach volleyball, however there are much tighter regulations on the overhand pass in beach volleyball.
Attack
The attack, also known as the spike, is usually the third contact a team makes with the ball. The object of attacking is to handle the ball so that it lands on the opponent's court and cannot be defended. A player makes a series of steps (the "approach"), jumps, and swings at the ball.
Ideally the contact with the ball is made at the apex of the hitter's jump. At the moment of contact, the hitter's arm is fully extended above his or her head and slightly forward, making the highest possible contact while maintaining the ability to deliver a powerful hit. The hitter uses arm swing, wrist snap, and a rapid forward contraction of the entire body to drive the ball. A 'bounce' is a slang term for a very hard/loud spike that follows an almost straight trajectory steeply downward into the opponent's court and bounces very high into the air. A "kill" is the slang term for an attack that is not returned by the other team thus resulting in a point.
Contemporary volleyball comprises a number of attacking techniques:
- Backcourt (or backrow)/pipe attack: an attack performed by a back row player. The player must jump from behind the 3-meter line before making contact with the ball, but may land in front of the 3-meter line.
- Line and Cross-court Shot: refers to whether the ball flies in a straight trajectory parallel to the side lines, or crosses through the court in an angle. A cross-court shot with a very pronounced angle, resulting in the ball landing near the 3-meter line, is called a cut shot.
- Dip/Dink/Tip/Cheat/Dump: the player does not try to make a hit, but touches the ball lightly, so that it lands on an area of the opponent's court that is not being covered by the defense.
- Tool/Wipe/Block-abuse: the player does not try to make a hard spike, but hits the ball so that it touches the opponent's block and then bounces off-court.
- Off-speed hit: the player does not hit the ball hard, reducing its speed and thus confusing the opponent's defense.
- Quick hit/"One": an attack (usually by the middle blocker) where the approach and jump begin before the setter contacts the ball. The set (called a "quick set") is placed only slightly above the net and the ball is struck by the hitter almost immediately after leaving the setter's hands. Quick attacks are often effective because they isolate the middle blocker to be the only blocker on the hit.
- Slide: a variation of the quick hit that uses a low back set. The middle hitter steps around the setter and hits from behind him or her.
- Double quick hit/"Stack"/"Tandem": a variation of quick hit where two hitters, one in front and one behind the setter or both in front of the setter, jump to perform a quick hit at the same time. It can be used to deceive opposite blockers and free a fourth hitter attacking from backcourt, maybe without block at all.
Block
Blocking refers to the actions taken by players standing at the net to stop or alter an opponent's attack.
A block that is aimed at completely stopping an attack, thus making the ball remain in the opponent's court, is called offensive. A well-executed offensive block is performed by jumping and reaching to penetrate with one's arms and hands over the net and into the opponent's area. It requires anticipating the direction the ball will go once the attack takes place. It may also require calculating the best foot work to executing the "perfect" block.
The jump should be timed so as to intercept the ball's trajectory prior to it crossing over the net. Palms are held deflected downward about 45-60 degrees toward the interior of the opponents court. A "roof" is a spectacular offensive block that redirects the power and speed of the attack straight down to the attacker's floor, as if the attacker hit the ball into the underside of a peaked house roof.
By contrast, it is called a defensive, or "soft" block if the goal is to control and deflect the hard-driven ball up so that it slows down and becomes more easy to be defended. A well-executed soft-block is performed by jumping and placing one's hands above the net with no penetration into the opponent's court and with the palms up and fingers pointing backward.
Blocking is also classified according to the number of players involved. Thus, one may speak of single (or solo), double, or triple block.
Successful blocking does not always result in a "roof" and many times does not even touch the ball. While it’s obvious that a block was a success when the attacker is roofed, a block that consistently forces the attacker away from his or her 'power' or preferred attack into a more easily controlled shot by the defense is also a highly successful block.
At the same time, the block position influences the positions where other defenders place themselves while opponent hitters are spiking.
Dig
Digging is the ability to prevent the ball from touching one's court after a spike or attack, particularly a ball that is nearly touching the ground. In many aspects, this skill is similar to passing, or bumping: overhand dig and bump are also used to distinguish between defensive actions taken with fingertips or with joined arms.
Some specific techniques are more common in digging than in passing. A player may sometimes perform a "dive", i.e., throw his or her body in the air with a forward movement in an attempt to save the ball, and land on his or her chest. When the player also slides his or her hand under a ball that is almost touching the court, this is called a "pancake". The pancake is frequently used in indoor volleyball.
Sometimes a player may also be forced to drop his or her body quickly to the floor in order to save the ball. In this situation, the player makes use of a specific rolling technique to minimize the chances of injuries.
