In CPR, what is the compression to breath ratio?

In CPR for adults, the compression to breath ratio is 30 compressions for every 2 breaths. This ratio applies during the initial phase of CPR, especially in scenarios where two rescuers are present. The rationale behind this specific ratio emphasizes the importance of maintaining adequate blood circulation through chest compressions while also providing intermittent breaths to ensure oxygenation.

The 30-2 ratio allows for a consistent and efficient approach, maximizing the time spent performing compressions, which are critical for maintaining perfusion to vital organs. By focusing on delivering compressions frequently—30 in a row before providing breaths—it enhances the chances of reviving a person experiencing cardiac arrest. This method aligns with current CPR guidelines established by organizations such as the American Heart Association, which aim to optimize outcomes during resuscitation efforts.
