What is the ratio of chest compressions to breaths for 2 person CPR?

The correct ratio of chest compressions to breaths for 2-person CPR is indeed 30 to 2. In a dual-rescuer scenario, continuous chest compressions are highly emphasized to maintain blood circulation during cardiac arrest. A ratio of 30 compressions followed by 2 breaths allows for both effective chest compressions and timely ventilation without compromising the quality of compressions.

This method ensures that the victim receives a higher number of compressions, which is vital for maintaining blood flow to vital organs. The alternating roles of the rescuers help to prevent fatigue, allowing them to maintain effective compressions over an extended period.

The other given ratios do not align with current CPR guidelines, which emphasize the importance of achieving both high-quality chest compressions and adequate ventilation in a specific format, hence the necessity of the 30 to 2 ratio in this scenario.
