What is the proper rate for chest compressions during CPR?

The proper rate for chest compressions during CPR is between 100 and 120 beats per minute. This range has been established through extensive research and is based on ensuring the most effective blood circulation during cardiac arrest situations. Compressions at this rate are sufficient to facilitate optimal perfusion of vital organs, particularly the heart and brain, which are most susceptible to damage when blood flow ceases.

In this context, compressing at a rate lower than 100 beats per minute may not provide adequate circulation, while compressing faster than 120 beats per minute can be counterproductive as it may reduce the effectiveness of each compression, impairing perfusion. Additionally, maintaining a consistent rate within this recommended range helps rescuers to perform CPR effectively, ultimately increasing the likelihood of survival and recovery for the individual in need.
