When performing CPR, what is the optimal rate of compressions per minute?

In CPR, the optimal rate of compressions per minute is 100-120 compressions. This rate is based on guidelines established by organizations such as the American Heart Association and the American Red Cross, which aim to maximize blood flow to vital organs by ensuring that compressions are delivered effectively and efficiently.

A compressions rate within this range promotes adequate circulation while balancing the need to provide compressions that are firm enough yet not too rapid to cause fatigue in the rescuer, which can lead to diminishing quality in the compressions. Properly performed chest compressions at the recommended rate help maintain blood flow to the heart and brain during cardiac arrest, increasing the chances of survival and favorable outcomes.

Compressions below the specified optimal range may not provide sufficient blood flow, while rates exceeding this might compromise the effectiveness of each compression and lead to a lack of sufficient time for the heart to refill between compressions. This understanding emphasizes the importance of adherence to the recommended compression rate to ensure effective CPR delivery.
