An EMT is performing CPR on an adult patient in cardiac arrest. What is the recommended compression-to-ventilation ratio for a single rescuer?
- A5 compressions to 1 ventilation.
- B30 compressions to 5 ventilations.
- C15 compressions to 2 ventilations.
- D30 compressions to 2 ventilations.
Show answer & explanationAnswer & explanation
Correct answer: D. 30 compressions to 2 ventilations.
For a single rescuer performing CPR on an adult, the recommended compression-to-ventilation ratio is 30 compressions followed by 2 ventilations. This ratio balances the need for effective chest compressions with adequate oxygenation.
Why the other options are wrong
- A. 5:1 is an outdated ratio and not currently recommended.
- B. 30:5 is not a standard recommended ratio for adult CPR.
- C. 15:2 is the ratio for two-rescuer CPR in children and infants, not single-rescuer adult.
Adult CPR Compression-to-Ventilation Ratio
The number of chest compressions performed for every set of rescue breaths during cardiopulmonary resuscitation (CPR) for an adult.
- For single-rescuer adult CPR, the ratio is 30:2.
- Compressions should be at least 2 inches deep.
- Rate of 100-120 compressions per minute.
- Minimize interruptions to compressions.
Memory trick: Adult's arrest, 30-2 is best!
