What is the recommended rate of chest compressions per minute?

The recommended rate of chest compressions per minute during cardiopulmonary resuscitation (CPR) is between 100 and 120 compressions. This guideline is established based on research indicating that this range is effective for maintaining adequate blood circulation to vital organs during a cardiac arrest. The compressions need to be performed at a consistent rate, as studies show that compressions within this range improve patient outcomes by ensuring sufficient blood flow.

Maintaining the correct rhythm is crucial because at rates lower than 100 compressions per minute, the effectiveness of blood circulation can decrease. Conversely, rates that exceed 120 compressions per minute may lead to a reduction in the depth of compressions, which is also detrimental. Thus, the specified rate not only optimizes perfusion but also aligns with established CPR guidelines to enhance the chances of survival after cardiac arrest.
