What is the recommended adult CPR compression-to-ventilation ratio when there is a single rescuer?

Explanation:
In adult CPR for a single rescuer, the goal is to maintain blood flow while providing ventilation. The standard cycle is 30 chest compressions followed by 2 rescue breaths. This ratio delivers enough circulatory support to keep perfusion going, while still giving breaths to oxygenate the blood without interrupting compressions for too long. The brief, effective breaths after 30 compressions minimize the time without chest compressions, helping maintain cerebral and coronary perfusion. Keep the pace around 100–120 compressions per minute and resume compressions immediately after the two breaths, ensuring full chest recoil between compressions.
