What is the compression-to-ventilation ratio in CPR for adults with no pulse?

• A. 15 compressions to 2 breaths
• B. 20 compressions to 2 breaths
• C. 30 compressions to 2 breaths
• D. 10 compressions to 2 breaths

Answer: (C)

In adult CPR with no pulse, the priority is to keep blood moving while adding enough oxygen. The recommended pattern is thirty chest compressions followed by two rescue breaths. This 30:2 rhythm balances delivering continuous blood flow with periodic breaths to oxygenate, without pausing too long for breaths and risking a drop in perfusion. Deliver compressions at about 100–120 per minute with a depth of about 2 inches (5 cm) and allow full chest recoil between pushes. If an advanced airway is in place, some guidelines shift to continuous compressions with one breath every six seconds, but the 30:2 approach is the standard when no advanced airway is used.
