Cardiac massage is an emergency practice to try to keep a person alive after his heart has stopped beating. Signs of cardiac arrest
are simple enough to identify: the person is lifeless, not breathing, and has no pulse. Emergency services should be immediately called in this case via 911. No heartbeat can be heard upon auscultation, and this reveals the utmost urgency. Cardiac massage is a technique sometimes used to restart the heart muscle
, or supplement its function pumping blood
, enabling the circulation of the blood through the aorta
towards the vital organs. It roughly consists of applying pressure rhythmically and vigorously on the upper chest, at a frequency of 100 per minute. Meanwhile, in the absence of spontaneous breathing, mouth
-to-mouth resuscitation should be practiced to ensure ventilation. In the absence of specialized medical care, cardiac massage should be done in the form of 30 pulses alternating with 2 breaths. This technique should not be stopped before help arrives, and should be known to everyone. According to statistics, in 80% of cases, the person who has to face this situation will be a friend or family member.
