When should you pause CPR to check rhythm with the AED?

• A. Every 30 seconds
• B. Only for rhythm analysis or pad replacements; otherwise keep chest compressions ongoing
• C. After every breath
• D. Never check rhythm

Answer: (B)

The key idea is to minimize interruptions to chest compressions. With an AED, you pause only when the device is analyzing rhythm or when you need to replace or reposition pads. The device will perform the rhythm analysis automatically and tell you if a shock is indicated. After a shock, resume CPR immediately as directed. If you’re not changing pads or awaiting an analysis, keep compressions going. Pausing every 30 seconds isn’t necessary because rhythm checks aren’t on a fixed schedule; they occur when the AED analyzes. Pausing after every breath isn’t how rhythm checks are done with the AED. Never checking rhythm contradicts how the AED determines whether a shock is needed.
