What is the recommended compression to breath ratio for single-rescuer adult CPR?

The recommended compression to breath ratio for single-rescuer adult CPR is 30 compressions to 2 breaths. This ratio is designed to maximize the chances of survival for a victim experiencing cardiac arrest by ensuring that there is continuous and effective chest compressions, which are crucial for maintaining blood flow to vital organs.

In this approach, performing 30 compressions followed by 2 breaths allows for a good balance between providing oxygen via rescue breaths and maintaining adequate blood circulation through compressions. This method is supported by current CPR guidelines, which emphasize hands-only CPR where compressions are prioritized. The 30:2 ratio is particularly effective in the single-rescuer scenario, as it allows for rapid and efficient resuscitation efforts without prolonged interruptions that can decrease the time spent on vital compressions.

Other compression to breath ratios, such as 15:2 or 10:1, do not align with the current guidelines intended to enhance lifesaving procedures for adults in cardiac arrest. Therefore, the 30:2 ratio is the standard practice recommended for one-rescuer adult CPR.
