What is the compression-to-ventilation ratio for two-rescuer CPR on an adult?

• A. 30 compressions to 2 ventilations.
• B. 2 compressions to 30 ventilations
• C. 15 compressions to 2 ventilations
• D. 5 compressions to 1 ventilation

Answer: (A)

In two-rescuer adult CPR, the goal is to keep blood flowing while still delivering oxygen. The most effective cycle is to perform 30 chest compressions, then give 2 rescue breaths, and repeat. This 30:2 pattern balances the need to maintain perfusion with the need to oxygenate the blood, coordinating roles between the rescuers so compressions stay continuous as much as possible and breaths come in only after those 30 compressions. Remember to keep the compressions at a rate of about 100 to 120 per minute and to deliver each breath quickly enough to produce chest rise. If an advanced airway is in place, the approach shifts to continuous compressions with breaths every 6 seconds, but for the standard two-rescuer scenario, 30 compressions to 2 breaths is the correct pattern.
