What is the recommended compression-to-breath ratio for adult CPR according to Orange County protocols?

The recommended compression-to-breath ratio of 30 compressions to 2 breaths for adult CPR is grounded in the guidelines established by the American Heart Association and endorsed by EMS protocols in many regions, including Orange County. This ratio emphasizes the importance of providing high-quality chest compressions while minimizing interruptions to maintain blood flow and oxygenation to vital organs during cardiac arrest.

This 30:2 ratio strikes a balance between delivering effective compressions, which help circulate blood, and providing rescue breaths, which supply oxygen to the lungs. It has been shown to enhance the chance of survival and successful resuscitation compared to older ratios, such as 15:2, which has been largely phased out in adult CPR guidelines due to studies that have demonstrated the effectiveness of a higher number of compressions within the same time frame.

In a practical scenario, the 30:2 ratio allows for delivering more compressions, which is critical as the heart needs rapid and consistent mechanical pumping to potentially reset its rhythm. This approach aligns with contemporary EMS practices, emphasizing efficiency and efficacy in emergency responses.
