What is the recommended rate of chest compressions per minute during CPR?

The recommended rate of chest compressions during CPR is 100 to 120 compressions per minute. Choosing 100 compressions as the answer aligns with best practices established by organizations like the American Heart Association. This guideline ensures that a sufficient blood flow is maintained to vital organs during cardiac arrest.

Maintaining a rhythm of chest compressions within this range not only maximizes circulation but also increases the chances of survival with favorable neurological outcomes. Properly performed compressions should be at a depth of about 2 to 2.4 inches for adults, and the rate allows for optimal venous return and coronary perfusion pressure.

While higher rates like 120 compressions per minute may also be considered correct in practice, the choice of 100 as a valid answer can often stem from various training courses and guidelines that emphasize starting at this frequency, allowing for consistency and ease of execution under stress.
