What is the appropriate compression-to-ventilation ratio for adult CPR?

The appropriate compression-to-ventilation ratio for adult CPR is 30 compressions to 2 breaths. This guideline is based on current resuscitation protocols, which emphasize the importance of high-quality chest compressions in restoring circulation during cardiac arrest.

Having a ratio of 30:2 allows for effective and efficient compression because it provides a consistent method for lay rescuers and healthcare providers to perform CPR. This ratio supports the need to maintain blood flow through thorough and rapid chest compressions, which should be delivered at a rate of 100 to 120 compressions per minute.

The reason for choosing this specific ratio is that the compressions help to circulate the blood, while the breaths ensure that oxygen is being delivered to the lungs and subsequently to the rest of the body. Maintaining this balance is crucial for providing effective life support until advanced medical help arrives.

By following this standard, rescuers can maximize the chances of survival for a patient experiencing cardiac arrest. This ratio is widely adopted and recognized in both the American Heart Association (AHA) and other emergency response protocols.
