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

The recommended compression to ventilation ratio in CPR for adults is 30 compressions to 2 breaths. This ratio is established by guidelines provided by health organizations, including the American Heart Association, emphasizing the importance of high-quality chest compressions to maintain blood circulation during cardiac arrest.

The 30:2 ratio is designed to ensure that an adequate number of chest compressions are delivered to generate blood flow, while still providing ventilations when breaths are given. The rationale for prioritizing compressions is that they are vital for maintaining cardiac output, and the 30 compressions allow for an effective rhythmic pattern that supports optimal circulation, especially in scenarios like sudden cardiac arrest where time is of the essence.

The use of this ratio reflects an understanding that while breaths are important for oxygenation, immediately resuming compressions is crucial for survival chances, which is why this specific ratio is taught in CPR training.
