During two-person adult CPR, what is the recommended compression-to-ventilation ratio?

In two-person adult CPR, the goal is to keep blood flowing while providing oxygen, so the cycle is 30 chest compressions followed by 2 rescue breaths. Perform compressions at about 100–120 per minute with a depth of about 2 inches (5 cm) and allow full chest recoil. After 30 compressions, give 2 breaths, each lasting about 1 second, watching for chest rise. This 30:2 rhythm balances maintaining perfusion with delivering sufficient ventilation. If an advanced airway is already in place, guidelines shift toward continuous compressions with one breath every 6 seconds, but for standard two-rescuer CPR, the 30:2 pattern is used.
