When should a mechanical CPR device be placed?

• A. Immediately at the start
• B. After the first four cycles (8 minutes)
• C. Only after ROSC
• D. Never use a mechanical device

Answer: (B)

The main idea is to keep chest compressions continuous and high quality. A mechanical CPR device helps sustain consistent compressions during long runs or while rescuers need to attend other tasks, but it should not delay the initial critical phase of manual CPR. Starting manual compressions right away and then, after about four cycles (roughly eight minutes), deploying the device allows the team to maintain high-quality compressions without interrupting early interventions such as rhythm checks, defibrillation if indicated, airway management, and IV/IO access. Deploying the device after eight minutes gives manual CPR a solid start and lets rescuers switch to a device-based, uninterrupted rhythm, which is especially helpful during transport or prolonged resuscitation. It’s not used after ROSC because ongoing CPR isn’t needed once circulation is restored, and you wouldn’t place a device to perform CPR if CPR isn’t being delivered.
