Switching responders during CPR should happen to preserve high-quality chest compressions and reduce fatigue. When more than one trained responder is available, switch roles approximately every 2 minutes, or after completing five cycles of 30 compressions and 2 breaths. You should also switch immediately if the current rescuer shows signs of fatigue or if compression quality declines, or when an AED is about to analyze or deliver a shock. Key guidelines
- Track time: Use a timer to switch every 2 minutes, or after 5 CPR cycles.
- Monitor quality: If compression depth falls below 2 inches (about 5 cm) or the rate drops below 100–120 compressions per minute, switch sooner.
- Fatigue signs: Heavy breathing, decreasing recoil, and visibly increasing effort warrant an immediate switch.
- AED rhythm checks: During pauses for rhythm analysis or shock delivery, coordinate the switch so compressions resume promptly after the AED action.
- Role distribution: One rescuer continues chest compressions; the other handles AED setup or rhythm checks. Upon switching, the roles reverse so both maintain hands-on time and minimize interruptions.
Practical tips
- Practice smooth transitions: Agree on a clear verbal cue and a brief handoff routine to minimize hands-off time.
- Readiness: The AED operator should be prepared to take over chest compressions during cycles or after shocks, maintaining continuous perfusion.
- Local protocols: Always align with your local CPR guidelines and the specific training you have completed.
If you’d like, I can tailor these guidelines to a specific scenario (e.g., two responders in a workplace vs. a home setting) or summarize official guidelines from a certifying organization.
