What is the recommended rate of chest compressions during CPR?

The recommended rate of chest compressions during CPR is 100 to 120 compressions per minute. This rate is essential to maintain adequate blood flow to vital organs during cardiac arrest. CPR guidelines emphasize that this compression rate helps achieve optimal circulation by mimicking the natural rhythm and pressure of a pumping heart. Compressing at this rate allows for more effective blood flow, improving the chances of survival and better outcomes for the patient.

The goal of CPR is to provide blood flow to the brain and heart until advanced medical care can take over. Research shows that compressions delivered at this rate strike a balance between providing sufficient blood circulation while ensuring compressions can be performed continuously without excessive fatigue.

Variations outside this range, such as compressions below 100 per minute, can result in inadequate perfusion pressure, while compressions above 120 per minute may lead to ineffective compressions due to decreased depth or fatigue, which can ultimately hinder the effectiveness of the CPR being performed. Thus, adherence to the recommended rate is critical in emergency situations.
