What is the CPR compression-to-breath ratio for adults?

The correct compression-to-breath ratio for adult CPR is defined as 30 compressions followed by 2 breaths. This ratio is recommended to ensure a continuous flow of oxygen to the brain and vital organs while minimizing interruptions to chest compressions. The focus on providing high-quality chest compressions is crucial in an emergency, as they help circulate blood to maintain a perfusion pressure until advanced help arrives or the patient revives.

This compression-to-breath ratio is based on current guidelines from organizations like the American Heart Association and is applicable for both trained lay rescuers and healthcare professionals when performing CPR on adults. The decision to use this specific ratio reflects an understanding of the need for optimal blood circulation during cardiac arrest scenarios.

Other options suggest different ratios which do not align with the established guidelines for adult CPR. An emphasis on reducing interruptions for breaths and maintaining effective compressions underscores why 30 compressions followed by 2 breaths is the standard practice.
