Cardiopulmonary resuscitation whether artificial respiration should be based on the ability of the rescuer to distinguish between the following cases: 1, if the medical staff have artificial respiration of the standard treatment, you can give the patient artificial respiration; 2, if the people, such as non-medical workers, you can not use artificial respiration, only bare hand heart compression can be. Unarmed cardiac compression can be done without artificial respiration, there are tests in this regard in foreign countries, that is, unarmed artificial cardiac compression, not accompanied by artificial respiration and accompanied by artificial respiration and cardiac compression of this cardiopulmonary resuscitation success rate is not much difference. Especially in the first few minutes, there is oxygen stored in the circulating blood, and this oxygen can provide blood supply and oxygen supply to the vital organs for a few minutes. Therefore, effective CPR can be performed within a short period of time with only cardiac compressions and without artificial respiration.
