How to successfully revive someone after cardiac arrest

Cardiac arrest generally requires immediate cardiopulmonary resuscitation (CPR) to save the patient's life. At the scene of the incident, chest compressions and artificial respiration should be administered immediately. This form of emergency treatment primarily helps maintain the patient's respiratory and circulatory functions, and within certain limits, can improve blood supply to the brain to some extent. Artificial respiration ensures a certain level of oxygen supply, which makes it possible for the patient to regain normal function.
