What You Need to Know About Cardiopulmonary Resuscitation Cardiopulmonary resuscitation or CPR is a life-saving technique and useful in an emergency. It is used when someone stops breathing and/or their heartbeat has stopped. The American Heart Association says everyone should start CPR with chest compressions. The American Heart Association recommends that if you are not trained, you perform chest compressions only (described later). If trained, start with chest compressions instead of checking the airway and start with rescue breathing. If trained but for a while, simply do chest compressions at 100 per minute. The instructions below are for adult CPR. Before you start• Check if the scene is safe before you are, so you don't get hurt trying. If an AED is available and five cycles into the CPR process, the person has not started to move, apply the AED and follow the required instructions. Administer one shock, then continue CPR starting with chest compressions for an additional two minutes before administering the second shock. A. If not trained with an AED, the 911 operator or other emergency medical personnel may be able to instruct you in how to use it.b. If no AED is available, go to step 55. Continue the CPR cycle until signs of movement appear or until emergency medical services (EMS) arrive. CPR on a ChildCPR for a child between the ages of 1 and 8 is essentially the same as for an adult, but below are the differences between the two.1. If you perform five cycles of compressions and breaths on your baby on your own, it should take about two minutes. Then call 911 and/or use an AED.2. Use one hand to perform chest compression and breathe more gently.3. Use the same compression-breath rate used with adults, 30 compressions with two breaths to complete the cycle.4. Use the AED if available after five cycles, apply it and follow the instructions it requires. If available, use pediatric electrodes, but if they are not available, use adult electrodes. Do not use the AED on children under one year of age. Follow the same steps as using the AED for an adult.5. Continue until help arrives or until the child moves. CPR for aPlace the child on a flat, firm surface2. Imagine a horizontal line between the baby's nipples. Place two fingers of one hand just below this line and in the center of the child's chest.3. Carefully compress your chest about 1.5 inches.4. Count aloud during compressions at a rate of 100 compressions per minute. Phase Two: Airway1. After 30 compressions carefully perform the head tilt-chin lift as described above.2. No more than 10 seconds to check if the baby is breathing by observing chest movements and breathing sounds. Phase Three: Breathing1. Cover the baby's nose and mouth with your mouth2. Give a rescue breath by using your cheeks to gently deliver puffs of air to slowly breathe into the baby's mouth at once. Watch to see if the chest rises, if the chest rises take the second breath. If the chest does not rise, repeat the head tilt-chin lift maneuver and take the second breath.3. If the baby's chest is still rising, examine the mouth for a foreign object inside. If you see an object, sweep it away with your finger. If the airway is blocked, administer first aid
