What is the recommended rate for adult chest compressions?

The recommended rate for adult chest compressions during cardiopulmonary resuscitation (CPR) is 100 to 120 compressions per minute. The guideline of 110 compressions per minute gives a precise target within that range that is effective for maintaining blood flow during cardiac arrest. This compression rate has been shown through research to optimize outcomes by ensuring adequate circulation without compromising the technique.

Other options, while having the specified rates, either fall below or exceed the optimal range recognized by CPR guidelines. A rate that is too slow may not provide sufficient blood flow to vital organs, while a rate that is too fast can lead to decreased effectiveness in generating blood flow and potentially increase the risk of injury to the ribcage. Hence, the choice of 110 compressions per minute aligns closely with best practices for CPR, valuing the balance between efficacy and safety during resuscitation efforts.
