What are CPR ratios if AED is not available?

• A. 15 compressions followed by 2 breaths
• B. 30 compressions followed by 2 breaths
• C. 60 compressions followed by 2 breaths
• D. 20 compressions followed by 2 breaths

Answer: (B)

When performing CPR without an AED, the recommended cycle for an adult is to deliver 30 chest compressions, then give 2 rescue breaths, and repeat. This 30:2 ratio optimizes blood flow to vital organs while providing just enough breaths to oxygenate the lungs without causing long interruptions in compression. Too few compressions would reduce perfusion, and too many breaths or too frequent pauses for ventilation would disrupt the circulation.
