When performing CPR, what is the compression-to-ventilation ratio for an adult?

• A. 15:2
• B. 30:2
• C. 30:1
• D. 20:2

Answer: (B)

In adult CPR, the recommended compression-to-ventilation ratio is 30:2. This means that for every 30 chest compressions, you should provide 2 rescue breaths. This ratio emphasizes the importance of maintaining a high-quality, uninterrupted compression rhythm which is crucial for circulating blood to the brain and vital organs during cardiac arrest. The compressions should be performed at a rate of 100-120 compressions per minute. After every 30 compressions, the rescuer pauses briefly to deliver 2 rescue breaths before continuing with more compressions. This cycle of 30 compressions followed by 2 breaths continues until emergency medical services arrive or an automated external defibrillator (AED) is available. Using the correct ratio is essential for ensuring effective CPR and improving the chances of survival for the patient experiencing cardiac arrest.
