Cardiopulmonary resuscitation (CPR) is a sequence of ventilations and chest compressions designed to maintain a casualty’s circulation.
Broadly speaking, a lay-rescuer should start CPR when a patient is found to be unresponsive and there are no signs of breathing (or agonal breathing is present). If trained to take a carotid pulse, CPR should be initiated when a patient is found to be unresponsive, not breathing (or only agonal breathing), and carotid pulse is absent during a brief (<10 second) pulse check.
? For an adult, CPR intervention may begin as soon as 911 has been called for an unresponsive, non-breathing casualty
? Children/Infants should receive 2 min of CPR before leaving to call 911
