Cardiopulmonary resuscitation is a series of first aid for cardiac massage and artificial respiration for people in cardiac and respiratory arrest. The earlier the resuscitation is performed, the higher the survival rate. half of the people may be saved within 4 minutes of resuscitation, starting from 4-6 minutes, 10% can be saved, >6 minutes survival rate is only 4%, more than 10 minutes, almost none of them survive. Once such an emergency, it is impossible to immediately appear around the medical staff, to wait for the medical staff to Lei before doing, that will sit and miss a good opportunity. We have to be like the children of the Wang family, without delay, immediately into rescue! CPR is not difficult to learn, everyone can do. The patient lies flat, shoulder pads, so that the head back, and the jaw up, can open the airway. Pinch the nostrils and blow into the patient’s mouth with your own mouth, which is artificial respiration. The heart massage method is to place the palm of one’s left hand on the lower part of the patient’s sternum, press the right hand on top of one’s left hand, and press hard, 80-100 times per minute/minute. In recent years Lei international does not advocate the need for ventilation, the rescuer does not want to or will not do blowing then can be immediately connected to continuous chest massage. Comparison studies, the effect is no less than those who have ventilation. Therefore, “hands-only CPR”, more convenient for everyone to learn. When such an accident occurs, the first thing to do is to immediately call the 120 emergency number, heart compressions can not stop until the professional emergency personnel to Lei take over the shift before handing over.
