A comparison of CPR delivery with various compression-to-ventilation ratios during two-rescuer CPR

A 15:2 compression-to-ventilation ratio when performed during two-rescuer CPR results in 26 s of hands off time each minute while only delivering 60 compressions. Alternative C:V ratios of 30:2, 40:2, 50:2, and 60:2 all exceed the AHA recommended 80 compressions/min while still delivering a minute volume in excess of 1 l.
