What is the recommended compression-to-ventilation ratio for adults during CPR?

The recommended compression-to-ventilation ratio for adults during CPR is 30:2. This ratio indicates that for every 30 chest compressions, 2 rescue breaths should be given. This approach is based on evidence that emphasizes the importance of high-quality chest compressions, which are critical for maintaining circulation and oxygenation during cardiac arrest.

The 30:2 ratio allows for a balance between providing adequate circulatory support through compressions and ensuring that the airway is managed effectively with ventilations. The goal is to maximize perfusion to vital organs while minimizing interruptions in chest compressions, which is crucial for increasing the chances of a favorable outcome.

This method is supported by guidelines from organizations such as the American Heart Association and the European Resuscitation Council, which advocate for compressions to be the priority in cardiac arrest situations. As a result, the 30:2 ratio has become the standard for adult CPR training and practice.
