Under the DOA policy, what is the reduced resuscitation duration if ET or King airway is in place and ETCO2 < 10?

Explanation:
End-tidal CO2 is a real-time indicator of perfusion during CPR, and having an advanced airway (ET tube or King) allows reliable capnography reading. When the airway is in place and ETCO2 is less than 10, this signals extremely poor perfusion and a very low chance of return of spontaneous circulation. The DOA policy accounts for this by setting a reduced resuscitation duration of 20 minutes under these conditions, balancing the futility of prolonged CPR with the opportunity that might exist if the threshold improves. If ETCO2 were not this low, the policy’s standard durations would apply and resuscitation could continue longer.
