At what rate should chest compressions be delivered in adult CPR?

In adult CPR, chest compressions should be delivered at a rate of 100 to 120 compressions per minute. This rate is important because research and guidelines have shown that effective chest compressions can significantly improve the chances of survival for a cardiac arrest victim. Performing compressions within this recommended range helps to maintain adequate blood flow to the heart and brain, which is crucial for preserving organ function until further medical help arrives. This optimal range ensures that both the quality and frequency of compressions are sufficient to facilitate perfusion and reduce the likelihood of complications during resuscitation efforts.
