What is the compression-to-ventilation ratio for a single provider during adult CPR?

The compression-to-ventilation ratio for a single provider during adult CPR is 30:2. This means that for every 30 chest compressions provided, the rescuer should give 2 rescue breaths. This ratio is designed to optimize blood circulation and oxygenation during cardiac arrest.

The reason for using 30 compressions followed by 2 breaths is based on research demonstrating that this method helps maintain adequate circulation and improves the chances of survival in adult patients experiencing a cardiac event. By performing 30 compressions first, the rescuer maximizes the amount of blood that is being circulated to vital organs before delivering breaths, which are also essential for increasing oxygen levels in the blood.

This compression-to-ventilation ratio is widely recommended and taught in courses like BLS for Health Care Providers because it aligns with current guidelines from organizations such as the American Heart Association. Understanding and applying this ratio correctly is crucial for effective CPR intervention.
