What ratio of compressions to breaths is recommended for adult CPR?

The recommended ratio of compressions to breaths for adult CPR is 30:2. This means that for every 30 chest compressions delivered, two rescue breaths should follow. This ratio is crucial because it balances the need for blood circulation through compressions with the requirement for oxygenation through breaths.

In adult CPR, where the primary cause of cardiac arrest is often related to a heart issue, the focus is on quickly restoring blood flow and oxygen to vital organs. The 30:2 ratio facilitates a higher number of compressions, which helps maintain circulation, while still ensuring that oxygen is delivered to the lungs through the rescue breaths.

This approach is supported by guidelines from organizations such as the American Heart Association (AHA), which emphasize the importance of high-quality chest compressions and regular, timely breaths to increase the chances of survival and brain function in a cardiac arrest victim. Maintaining this ratio helps ensure that CPR is both effective and efficient, providing the best possible outcome for the patient.
