Which action is recommended to minimize interruptions during CPR in a field setting?

• A. Check for a pulse and breathing for 60 seconds
• B. Begin CPR only after confirming a shockable rhythm with AED
• C. Initiate CPR immediately and apply an AED if available; minimize interruptions and evacuate as needed.
• D. Delay CPR to reassess after every minute

Answer: (C)

In field CPR, the priority is to maximize blood flow to vital organs by delivering continuous, high-quality chest compressions while bringing in an AED as soon as possible and only moving to safety or advanced care when necessary. Starting CPR immediately keeps perfusion going, which is crucial for brain and heart survival. If an AED is available, apply it right away and follow its prompts; the device will analyze the rhythm and deliver a shock if indicated, but you should resume chest compressions immediately after the shock to maintain circulation.

Minimizing interruptions is essential because each pause disrupts the flow of blood to the heart and brain, reducing the chances of survival. Evacuation should be done only when required for safety or to obtain more advanced care, and even then you should continue CPR if you can, or coordinate with others to keep compressions going while moving.

Delaying CPR until you confirm a shockable rhythm, or spending long periods confirming pulse or breathing, or pausing to reassess after every minute, interrupts perfusion and lowers the likelihood of a good outcome. The recommended approach is to start compressions right away, use the AED as soon as it’s ready, and evacuate only as needed while maintaining compressions.
