CPR is an acronym for Cardiopulmonary resuscitation, which is a first aid technique for a victim who is unable to breathe on his/her own. It involves giving mouth-to-mouth respiration, chest compressions and lung ventilation. Upon arriving at the scene of an accident, you would first ascertain if the patient is breathing and if there is a pulse. If not, this form of artificial respiration is intended to get the heart pumping and the person breathing again. First you have to make sure there is no obstruction to the airways causing the stoppage of breathing.

To administer CPR, you tilt the head back and listen for breathing. Pinch the victim’s nose and place your mouth over the victim’s, giving two short breaths. Each breath should take about one second. Watch to see if the victim’s chest rises. If the victim is still not breathing, start giving chest compressions. To do this you place your hands on the chest between the nipples, with one hand over the other. Push down on the chest to a depth of about 1.5 to 2 inches. Do this 30 times. Then check to see if there is any breathing. Repeat with the artificial respiration and the chest compressions until medical help arrives.

CPR for children is not the same as that for adults. If you have to administer CPR to a child, use only the heel of one hand to give the compressions and do not push as deeply into the chest. For babies, you first try to get the baby awake by shouting and tapping. Open the airway by tilting the head back, but do not tilt it back too far. Cover the baby’s nose and mouth with yours and give two short, gentle breaths. Use only two or three fingers to give chest compressions and repeat the breathing if necessary.
