How do the compression to breath ratios change with the number of rescuers for Adult CPR?

In adult CPR, the compression to breath ratio remains consistent regardless of the number of rescuers. The standard ratio for adult CPR performed by one or two rescuers is 30 compressions to 2 breaths. This ratio is maintained to ensure that the focus during resuscitation remains on providing effective chest compressions, which are critical for maintaining circulation.

Even when additional rescuers are present, the goal is to keep the technique simple and standardized to avoid confusion and ensure effective care. While more rescuers can take turns performing compressions or providing breaths to prevent fatigue, the fundamental ratio of compressions to breaths does not change. Thus, having more rescuers involved does not alter the established compression to breath ratio set for adult victims.
