Cardiopulmonary resuscitation, or basic life activity support, should be performed immediately when cardiac arrest is determined.
The first step in determining cardiac arrest is to determine whether there is voluntary consciousness, and to quickly check whether breathing is present or can be normal, and to determine whether there is an arterial beat, which needs to be accomplished within 5 to 10 seconds. Cardiopulmonary resuscitation (CPR) should be performed immediately after the determination of cardiac arrest.
Cardiopulmonary resuscitation (CPR) is the key to the recovery of autonomic circulation in patients with cardiac arrest, and should be initiated as soon as cardiac arrest is detected in order to avoid systemic ischemic injury. If cardiopulmonary resuscitation is not timely, the patient will enter a more serious and complex phase of reperfusion injury after experiencing ischemic injury, so timely cardiopulmonary resuscitation is a key measure to reduce mortality.
It should be emphasized that fainting with loss of consciousness does not necessarily require CPR; CPR must be required when the aortic pulses are not palpable and cardiac arrest is considered.
