CPR</h3>
Cardiopulmonary resuscitation (CPR) is a life-saving emergency technique that involves giving someone who is having a cardiac arrest chest compressions and sometimes artificial ventilation in an effort to keep their brain functioning normally until additional steps are taken to bring back their breathing and spontaneous blood circulation. In people who are unresponsive and not breathing or who are breathing abnormally, such as experiencing agonal respirations, it is advised.
Adults who need CPR must perform chest compressions between the depths of 5 cm (2.0 in) and 6 cm (2.4 in) per minute, at a minimum.
By utilizing a machine that forces air into the subject's lungs or by exhaling into the subject's mouth or nose (mouth-to-mouth resuscitation), the rescuer can also offer artificial ventilation (mechanical ventilation).
