At what rate should chest compressions be delivered during CPR?

Chest compressions during CPR should be delivered at a rate of 100 to 120 compressions per minute. This rate allows for optimal blood circulation and is in line with guidelines established by organizations such as the American Heart Association. The rationale behind this rate is to ensure that enough compressions are provided to effectively maintain blood flow to vital organs, especially the brain and heart, thereby increasing the chances of survival following cardiac arrest.

Research has demonstrated that compressions delivered within this recommended range are associated with better outcomes in victims of cardiac arrest. Compressing too slowly (as in the first two options) may fail to enhance circulation adequately, while compressing too rapidly (as in the last option) can lead to ineffective compressions that do not allow sufficient time for the heart to refill with blood between compressions. Maintaining a consistent, efficient rate of 100 to 120 compressions per minute strikes the crucial balance needed for effective CPR.
