The ABC system for CPR training was later adopted by the American Heart Association, which promulgated standards for CPR in 1973. As of 2010, the American Heart Association chose to focus CPR on reducing interruptions to compressions, and has changed the order in its guidelines to Circulation, Airway, Breathing (CAB). [48]
Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation, or mouth to mouth in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
In the late 1970s the Heart-Aid was developed as the first truly automated external defibrillator that was designed for the public. The principles of ABC assessment and a human voice relaying instructions helped bystanders respond to a sudden cardiac event while waiting for the first responders to get to scene. [3]
After first 5 breaths, if effective, it is also advisable to search for signs such movements, coughing, shortness and possibly only the presence of pulse, for less than 10 seconds. [citation needed] if there are signs of circulation or a heart rate greater than 60 continue ventilations with a rate of 20 per minute.
By 1966, CPR was being taught to laypeople as well as professionals, but with disappointing results. Fewer than 50% of people were able to pass a CPR performance evaluation three months after receiving standardized training in CPR, and the results of cardiac resuscitation attempts initiated outside of hospitals were dismal.

Mouth-to-mouth resuscitation is a part of most protocols for performing cardiopulmonary resuscitation (CPR) [6] [7] making it an essential skill for first aid. In some situations, mouth-to-mouth resuscitation is also performed separately, for instance in near- drowning and opiate overdoses.
