As a single rescuer, what is the correct ratio of compressions to breaths during adult CPR?

In adult CPR, the correct ratio of compressions to breaths for a single rescuer is 30 compressions to 2 ventilations. This ratio is based on current guidelines which prioritize high-quality chest compressions as the primary focus in cardiac arrest situations. Each cycle of CPR should consist of 30 compressions followed by 2 rescue breaths, ensuring that the patient receives adequate oxygenation while maintaining sufficient blood flow during the compressions.

The rationale behind this specific ratio is to maximize the effectiveness of chest compressions by allowing a rapid return to compressions after delivering a few breaths, which is vital in improving survival outcomes. This method balances the need for oxygenation with the continuous flow of blood, which is essential during a cardiac emergency. By adhering to this ratio, rescuers can provide optimal care and increase the chances of a successful resuscitation.
