30-minute anchor: stop/continue huddle, not a rule.
Longer: witnessed/monitored, shockable/improving, reversible cause/bridge, ROSC signs.
Shorter: unwitnessed/unmonitored, unchanged asystole/PEA, no target/ROSC/bridge.
Guardrail: OHCA TOR rules do not automatically apply to IHCA.
Summarize: “[duration] CPR, persistent [rhythm], no ROSC, no remaining reversible intervention.”
Ask: “Anything we have not tried?”
Announce: “One final rhythm/pulse check; if unchanged, we stop CPR.”
What went well/not? What could we do differently? Does anyone need support?
