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

The recommended rate for chest compressions during CPR is between 100 to 120 compressions per minute. This range has been established based on research that shows a higher rate of chest compressions can help maintain blood circulation to vital organs during cardiac arrest. The goal of CPR is to provide effective circulation of oxygenated blood, and a compression rate within this range strikes a balance between being effective and maintaining the compressions without interruption for breaths.

Maintaining a rate of 100 to 120 compressions per minute allows for adequate time for the heart to refill with blood between compressions while ensuring that the compressions are performed with enough frequency and force to have a meaningful impact on blood flow. It’s important that rescuers aim for this optimal range to increase the chances of survival for the person experiencing a cardiac event.
