What is the correct adult compression-to-breath ratio during CPR?

The adult compression-to-breath ratio during CPR is 30 compressions to 2 breaths. This ratio is recommended for both single-rescuer CPR and multi-rescuer CPR for adults. The reasoning behind this specific ratio is based on the need to maintain high-quality chest compressions and effective ventilation to optimize blood flow and oxygen delivery to vital organs, particularly during a cardiac arrest situation.

Performing 30 compressions followed by 2 rescue breaths allows for continuous and effective blood circulation while also providing the necessary oxygenation. The emphasis on compressions is critical, as they are the primary means of maintaining circulation until advanced medical help arrives. The guidelines prioritize this ratio to ensure that the responder can perform adequate compressions while still integrating rescue breaths at a manageable interval, thus maximizing the chances of survival and a favorable outcome for the patient.
