In CPR, what is the ratio of chest compressions to breaths?

The ratio of chest compressions to breaths during CPR for adults is indeed 30 chest compressions to 2 breaths. This guideline is based on current resuscitation protocols that emphasize providing high-quality chest compressions to maintain blood flow while also delivering breaths to provide oxygenation.

In a typical CPR scenario for adults, the 30:2 ratio allows for a more effective rhythm that maximizes the chances of maintaining circulation and oxygen delivery. This approach was developed to streamline the process and ensure responders can maintain a consistent and quick rhythm, which is crucial during a life-threatening emergency. The focus on this specific ratio helps rescuers remember the critical importance of continuous chest compressions while also interspersing breaths for effective ventilation.
