How many press release cycles should you perform in closed heart chest massage per minute?

The correct answer emphasizes that during closed chest cardiac massage, the recommended frequency of press release cycles is between 60 to 80 per minute. This range is important because it aligns with guidelines established by the American Heart Association for effective cardiopulmonary resuscitation (CPR) and advanced life support.

Performing compressions at this rate ensures that blood circulation is maintained as effectively as possible during cardiopulmonary resuscitation, maximizing the chances of maintaining organ perfusion, especially to critical areas like the brain and heart.

This frequency facilitates effective circulation, allowing enough time for the chest to recoil between compressions, which helps create negative pressure that draws blood back into the heart and ensures adequate delivery of oxygen to the vital organs. A rhythm that is too slow would not provide adequate support, while a rhythm that is too fast may compromise the quality of compressions by shortening the necessary downtime for heart refill.
