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

The recommended compression-to-ventilation ratio for adult CPR is 30 compressions to 2 breaths. This ratio is emphasized in protocols as it helps to ensure that high-quality chest compressions are delivered while also providing sufficient oxygenation through ventilations.

In adult CPR, the main priority is to maintain blood circulation through adequate compressions. The ratio of 30:2 allows for a more effective rhythm that can be managed easily during resuscitation efforts, especially when performed by a single rescuer. This approach helps to maximize the time spent on compressions while providing the essential ventilations, facilitating both circulation and oxygenation, which are critical during cardiac arrest situations.

Other ratios, such as 15 compressions to 2 breaths, are not in standard practice for adults, as they can lead to less effective overall resuscitation. Similarly, other lower ratios might not provide the necessary balance between compressions and ventilations required for optimal patient outcomes during adult CPR.
