During high-quality CPR, when do pauses in chest compressions typically occur?

• A. Rhythm analysis
• B. Compressor switches
• C. Defibrillation
• D. Pulse checks

Answer: (C)

The main idea here is that the most common intentional interruption during high-quality CPR is to allow a shock when one is indicated. When a defibrillator or AED is used, the device must first analyze the heart rhythm and, if a shock is recommended, deliver that shock. That analysis-and-shock moment requires a brief pause in chest compressions so the device can determine the rhythm and deliver the treatment safely. After the shock is delivered, you resume compressions immediately and continue CPR. Other pauses, like switching rescuers or checking for a pulse, should be kept as brief as possible, and routine pulse checks aren’t part of the standard CPR cycle for adults unless there are signs of return of spontaneous circulation.
