What is the recommended rate of compressions for CPR?

The recommended rate of compressions for CPR is between 100 to 120 compressions per minute. This guideline is established to ensure that chest compressions are effective in maintaining blood flow to vital organs during cardiac arrest. Research shows that a compression rate within this range optimally balances the need for adequate circulation while allowing for sufficient time for the chest to recoil between compressions, which can enhance blood return to the heart.

Compressions performed at this rate also match the rhythm of many common songs, such as "Stayin' Alive" by the Bee Gees, which can serve as a helpful mental cue for those performing CPR. By maintaining the recommended compression rate, rescuers increase the likelihood of delivering effective CPR, potentially improving the chance of survival for the person in cardiac arrest.
