What is the compression to ventilation ratio for adult CPR?

The correct answer for the compression to ventilation ratio for adult CPR is 30:2. This means that for every 30 chest compressions performed, the rescuer should give 2 rescue breaths. This ratio is based on guidelines that prioritize high-quality compressions to maintain blood circulation while ensuring adequate ventilation to the victim.

This approach emphasizes the importance of performing compressions at an appropriate depth and rate to effectively circulate blood and oxygen in the absence of a heartbeat. The 30:2 ratio allows for an efficient cycle that helps maximize the chances of survival in a cardiopulmonary arrest scenario.

In an adult victim, the focus is primarily on maintaining circulation through compressions, with rescue breaths provided periodically to ensure the body receives oxygen. Understanding this ratio is crucial for anyone providing CPR in emergency situations, as it has been standardized to improve outcomes and is widely taught in CPR courses.
