During CPR, what is the recommended compression to rescue breaths ratio?

The recommended compression to rescue breaths ratio during CPR is 30:2. This means that for every 30 chest compressions delivered, there should be 2 rescue breaths given. This ratio has been established as effective in maintaining circulation and providing oxygen to someone experiencing cardiac arrest.

The rationale behind this approach is that high-quality chest compressions are the most critical component in increasing the chances of survival during cardiac emergencies. By using the 30:2 ratio, rescuers can focus on providing a sufficient number of compressions while still ensuring that ventilation is provided effectively. This balance helps to maximize blood flow and oxygenation in a time-sensitive situation.

In contrast, other ratios such as 15:1 and 50:5 provide either too few compressions or too few breaths, which could compromise the effectiveness of CPR. Maintaining an optimal ratio ensures that the patient receives adequate support until emergency medical services arrive or the individual starts to show signs of recovery.
