CPR in a Swimming Pool Environment
There is no place that the skill and training of lifesaving tactics come into play more than around a swimming pool. Accidents happen all the time. Drowning, heart attacks and injuries happen every day around pools and you should be ready and trained if you own a pool, or spend more than a few hours a week around a swimming pool. Here is a guide for performing CPR, and a few other rescue tips. This article is not a substitute for professional training, and is only a guide of procedures for performing CPR. Always be sure to have a working phone at the pool, and In case of medical emergency or serious injury, call 911 immediately.
· If a person has collapsed, determine if the person is unconscious. Gently prod the victim and shout, “Are you okay?” If there is no response, shout for help. Call 911 or your local emergency number.
· If the person is not lying flat on his or her back, roll him or her over, moving the entire body at one time.
· Open the person’s airway. Lift up the chin gently with one hand while pushing down on the forehead with the other to tilt the head back. (Do not try to open the airway using a jaw thrust for injured victims. Be sure to employ this head tilt-chin lift for all victims, even if the person is injured.)
· If the person may have suffered a neck injury, in a diving or automobile accident, for example, open the airway using the chin-lift without tilting the head back. If the airway remains blocked, tilt the head slowly and gently until the airway is open.
· Once the airway is open, check to see if the person is breathing.
· Take five to 10 seconds (no more than 10 seconds) to verify normal breathing in an unconscious adult, or for the existence or absence of breathing in an infant or child who is not responding.
· If opening the airway does not cause the person to begin to breathe, it is advised that you begin providing rescue breathing (or, minimally, begin providing chest compressions).
Breathing (Rescue Breathing)
Pinch the person’s nose shut using your thumb and forefinger. Keep the heel of your hand on the person’s forehead to maintain the head tilt. Your other hand should remain under the person’s chin, lifting up.
· Inhale normally (not deeply) before giving a rescue breath to a victim.
· Immediately give two full breaths while maintaining an air-tight seal with your mouth on the person’s mouth. Each breath should be one second in duration and should make the victim’s chest rise. (If the chest does not rise after the first breath is delivered, perform the head tilt-chin lift a second time before administering the second breath.) Avoid giving too many breaths or breaths that are too large or forceful.
Circulation (Chest Compressions)
After giving two full breaths, immediately begin chest compressions (and cycles of compressions and rescue breaths). Do not take the time to locate the person’s pulse to check for signs of blood circulation.
· Kneel at the person’s side, near his or her chest.
· With the middle and forefingers of the hand nearest the legs, locate the notch where the bottom rims of the rib cage meet in the middle of the chest.
· Place the heel of the hand on the breastbone (sternum) next to the notch, which is located in the center of the chest, between the nipples. Place your other hand on top of the one that is in position. Be sure to keep your fingers up off the chest wall. You may find it easier to do this if you interlock your fingers.
· Bring your shoulders directly over the person’s sternum. Press downward, keeping your arms straight. Push hard and fast. For an adult, depress the sternum about a third to a half the depth of the chest. Then, relax pressure on the sternum completely. Do not remove your hands from the person’s sternum, but do allow the chest to return to its normal position between compressions. Relaxation and compression should be of equal duration. Avoid interruptions in chest compressions (to prevent stoppage of blood flow).
· Use 30 chest compressions to every two breaths (or about five cycles of 30:2 compressions and ventilations every two minutes) for all victims (excluding newborns). You must compress at the rate of about 100 times per minute. It has been said that you can use the beat of the BeeGee's song "Staying Alive" as a tempo to proper CPR rythym.
· Continue CPR until advanced life support is available.
Using an AED in conjunction with CPR:
· If using an AED in the case of a heart attack or cardiac arrest, single shocks should be followed by immediate CPR for two minutes. Heart rhythm checks should be performed every two minutes (or after giving about five cycles of CPR); the AED will provide audible prompts at the appropriate intervals.
· If using an AED on a one- to eight-year-old child, use a child-dose-reduction system if available. (However, do not use child pads or a child dose on adults in cardiac arrest because the smaller dose may not defibrillate adults properly.)
CPR for Infants (Up to One Year Old)
With infants, be careful not to tilt the head back too far. An infant’s neck is so pliable that forceful backward tilting might block breathing passages instead of opening them.
Do not pinch the nose of an infant who is not breathing. Cover both the mouth and the nose with your mouth and breathe slowly (one to one and a half seconds per breath), using enough volume and pressure to make the chest rise.
With a small child, pinch the nose closed, cover the mouth with your mouth and breathe at the same rate as for an infant. Rescue breathing should be done in conjunction with chest compressions.
Chest Compressions on Infants
· If alone with an unresponsive infant, give five cycles of CPR (compressions and ventilations) for about two minutes before calling 911 or your local emergency number.
· Use only the tips of the middle and ring fingers of one hand to compress the chest at the sternum (breastbone), just below the nipple line, as described in the table below. The other hand may be slipped under the back to provide a firm support. (However, if you can encircle your hands around the chest of the infant, using the thumbs to compress the chest, this is better than using the two-finger method.)
· Depress the sternum between a third to a half the depth of the chest at a rate of at least 100 times a minute.
· Two breaths should be given during a pause after every 30 chest compressions (a 30:2 compression-to-ventilation ratio or two breaths about every two minutes) on all infants (excluding newborns).
· Continue CPR until emergency medical help arrives.
Small Children (ages one to eight)
· Give five cycles of CPR (compressions and ventilations) for about two minutes after calling 911.
· Use the heel of one or two hands, as needed, and compress on the breastbone at about the nipple line.
· Depress the sternum about a third to a half the depth of the chest, depending on the size of the child. The rate should be 100 times per minute.
· Give two breaths for every 30 chest compressions (30:2 ratio) or two breaths about every two minutes.
· Continue CPR until emergency medical help arrives.
