What is the compression-to-breaths sequence for an adult when a single rescuer performs CPR?

• A. 15 compressions to 2 breaths
• B. 30 compressions to 1 breath
• C. 20 compressions to 2 breaths
• D. 30 compressions to 2 breaths

Answer: (D)

In adult CPR performed by a single rescuer, the goal is to keep blood flowing while providing oxygen. The recommended sequence is 30 chest compressions followed by 2 rescue breaths. This 30:2 pattern strikes a balance between maintaining perfusion with continuous compressions and delivering enough breaths to oxygenate the blood, without causing excessive interruptions. The cadence should be about 100–120 compressions per minute with a depth of at least 2 inches (5 cm) for adults, switching to breaths after every 30 compressions. Two rescuers shift to a 15:2 ratio, but for a single rescuer, 30:2 is the standard. Other ratios like 20:2 or 30:1 aren’t the standard guidelines for one rescuer CPR.
