What is the correct compression to ventilation ratio for adult CPR?

The correct compression to ventilation ratio for adult CPR is 30 compressions to 2 breaths. This ratio is recommended by organizations such as the American Heart Association and is essential for maximizing the chances of survival in a cardiac arrest situation. Performing 30 compressions followed by 2 breaths allows for effective blood circulation and oxygenation of the victim's vital organs.

The rationale behind this particular ratio lies in the need to maintain continuous blood flow while minimizing interruptions. The emphasis on performing compressions at a rate of 100 to 120 compressions per minute means that the rescuer can efficiently deliver oxygen through rescue breaths without significantly delaying compressions.

Utilizing different ratios, such as 15 compressions to 2 breaths, could result in insufficient blood circulation and inadequate oxygenation during critical moments. Likewise, lower ratios like 10 compressions to 1 breath or 20 compressions to 2 breaths would also disrupt the balance of effective compressions and ventilations necessary during a cardiac event. Thus, adhering to the 30:2 ratio during adult CPR optimizes both chest compressions and rescue breathing, providing the best chance for survival and recovery.
