Cardiopulmonary Resuscitation Compression-to-Ventilation Ratio for Adults in Two-Person CPR

During two-rescuer cardiopulmonary resuscitation (CPR) for adults, the recommended compression-to-ventilation ratio is consistently 30:2. This means that for every 30 chest compressions, two rescue breaths should be administered. These ventilations can be delivered using a bag-mask device or mouth-to-mouth technique. Each cycle consists of five sets of 30 compressions and 2 ventilations, totaling 150 compressions and 10 breaths per full cycle.

Understanding the CPR Cycle

It's essential to understand that chest compressions take priority over rescue breaths in adult CPR. As such, each cycle begins with 30 compressions before moving on to ventilation. This emphasis on compressions ensures continuous blood flow to vital organs during cardiac arrest.

Reassessing the Patient After Each Cycle

After completing five cycles of 30:2 CPR, rescuers should pause to reassess the patient's condition. This includes checking for signs of restored breathing and circulation. If there's no response, CPR should resume immediately, continuing with the 30:2 ratio.

Key Considerations During CPR

Performing effective CPR requires coordination between rescuers. One person should focus on delivering high-quality chest compressions while the other manages airway and ventilations. Maintaining the correct rhythm and depth of compressions is crucial to maximize the chances of survival. Proper training and practice help ensure that both rescuers can work efficiently as a team during emergency situations.
