Cardiac arrest resuscitation methods, the most commonly used is cardiopulmonary resuscitation, because cardiac arrest, usually accompanied by respiratory arrest immediately, chest compressions and artificial respiration must be alternated. Chest compressions are usually performed by overlapping the palms of both hands and pressing the lower part of the patient’s sternum vertically, the depth of compressions must be 5-6 cm, and the frequency of compressions must be at least 100 times per minute to produce sufficient artificial circulation to supply blood to all organs and tissues of the body. And artificial respiration, usually are chest compressions 30 times, immediately after 2 times of artificial respiration, alternating. In addition, if the cardiac monitor, defibrillator, suggest that there is ventricular fibrillation, ventricular flutter, the use of electric defibrillation, using a certain amount of current to stimulate the heart muscles, so that the normal heartbeat is restored. Next is drug resuscitation, the most commonly used drug resuscitation is epinephrine, epinephrine can enhance the contractility of the heart muscle and is most effective in helping to restore the heartbeat. Usually 3 minutes after the application of a second heartbeat is not restored, the most commonly used can be the best intravenous push, if you can not immediately establish good intravenous access, you can also do intramuscular injection, subcutaneous injection.
