Here only a brief introduction, you can refer to CPR, cardiopulmonary resuscitation, CPR, life support.

Basic life support can be decomposed into the following steps: identifying cardiac arrest, emergency medical services system distress (EMSS), and cardiopulmonary resuscitation (airway (A), rescue breathing (B), to maintain the circulation (C), defibrillation (D)).
Identification

Intensive dubious persons, to protect themselves and in the case of patient safety, first identify patients with and without reaction. If a reaction occurs, breathing, will have to clear the condition, help, give the appropriate position (the patient's posture) such as the recovery position; If no response, they have to open the airway; without breathing, artificial respiration will have to give the recovery position, identification whether the cycle signs, give CPR if necessary.

Airway opening

Open airway for the treatment of coma, measures sudden death in children and choking disease is the first to be taken. The presence of foreign bodies can be removed, can also be used abdomen (chest) portion of the impact of law, coma should chest compressions. Open the airway by lifting the chin upward, often law, methods of operation that simultaneously push down his forehead lift up chin chin.

Artificial respiration

Artificial respiration in a closed airway open airway basis, pinch the nostrils closed when mouth to mouth, mouth to nose while pinching closed lips, mouth to mouth, nose or can endotracheal intubation, the use of balloon mask, so the mask must be afterburner and facial close and closed, while opening the airway. Blowing should slowly and evenly, with a small tidal volume with a time of 2 seconds, to avoid rapid impact, a lot of blowing. Blow should be visible chest lifted, then the chest down.

Chest compressions

Cardiac massage indications are lost consciousness no pulse, sudden cardiac death is often first pressing (after aeration), a clear rhythm of ventricular fibrillation or pulseless ventricular tachycardia, defibrillation as soon as possible. Operation method: kneeling on the ground, for the patient's chest, the base overlap in the middle of the palm of both breasts, i.e., the lower part of the sternum of the patient's finger to the left, straight elbows, shoulders firmly pressed down vertically, so that chest fell 3 ~ 5cm, then relax and let the sternum completely bounced back, relax hand when not ricochet off the chest wall,
In a push - to relax in, pressing, each half of the time to relax, do not impact or dough-like compressions. Pressing frequency of 100 times per minute, 30 times after every push to give vent 2. Minimize interference, fast, strong, continuous, uninterrupted pressed.
