The ventilation to compression ratio in CPR is given as what?

• A. 2-30
• B. 30-2
• C. 15-2
• D. 1-1

Answer: (A)

The main idea is how many breaths are given relative to chest compressions during CPR. For an adult with one rescuer, you perform 30 chest compressions and then give 2 rescue breaths. If you express that as ventilation-to-compression, it’s 2 breaths for every 30 compressions, written as 2-30. That’s why this option is correct: it reflects breaths per compressions, not compressions per breath. This pattern keeps blood flowing with minimal interruptions while still ensuring ventilation. The alternative ways of writing it would describe the opposite ratio (compressions to breaths) or apply to different rescuer configurations, which isn’t what the question is asking.
