Which statement best describes the use of mechanical CPR devices regarding interruptions?

• A. Delay application until after the first four cycles to minimize interruptions
• B. Apply immediately to avoid fatigue
• C. Use only after a shock has been delivered
• D. Never use a mechanical device

Answer: (A)

Mechanical CPR devices are meant to provide steady, high-quality chest compressions and reduce rescuer fatigue, but getting them in place takes a brief moment and can interrupt compressions. The best approach is to start with manual CPR and deploy the device after a short, uninterrupted period (often described as after the first few cycles) so that the handoff from manual to device is smooth and causes as few interruptions as possible. Once the device is running, compressions continue consistently, freeing rescuers to manage other tasks such as defibrillation, airway, or transport. Using the device immediately would introduce a pause to position it, and waiting until after a shock or never using it aren’t aligned with standard practice when a mechanical option is available.
