What is the compression-to-ventilation ratio for adult cardiopulmonary resuscitation by a lone rescuer?
Answer and explanation
Correct answer: C. 30 compressions to 2 breaths
- Step 1: Current guidelines use 30:2 for adults.
- Step 2: Compressions should be at 100-120 per minute.
Answer
30 compressions to 2 breaths.
Why not the others: '15 compressions to 2 breaths' is used for paediatric two-rescuer CPR; '5 compressions to 1 breath' is outdated; 'Continuous breaths without compressions' is incorrect.
