Cardiopulmonary Resuscitation (CPR) Practice 2025 - Free CPR Practice Questions and Study Tips.

The compression-to-breath ratio for adult CPR is 30:2, which is crucial for effective resuscitation. This means that for every 30 chest compressions delivered, 2 rescue breaths should be given. This ratio is designed to maximize blood flow to vital organs while minimizing interruptions in chest compressions, which are essential for maintaining circulation during cardiac arrest.

In adult CPR, using a 30:2 ratio helps maintain a higher level of perfusion pressure and increases the chances of sustaining vital organ function until more advanced medical help arrives. It is based on current guidelines which emphasize the importance of high-quality chest compressions and efficient delivery of rescue breaths.

This specific ratio is important because it has been shown to be the most effective for adult patients, balancing the need for compressions—which are the primary focus of CPR—with the necessity for ventilation. Following this established ratio ensures that the person receiving CPR has the best possible chance of survival and recovery.
