Aspects of the correct course of action on finding an unconscious diver underwater have been debated on internet forums. Should you try to replace the regulator?; should you wait until a seizure is finished before ascending?; what procedures should be used for a rebreather diver?; should you try to complete some decompression on a decompression dive?; should you try rescue breaths in the water at the surface?; and others.

The Diving Committee of the Undersea and Hyperbaric Medical Society recently completed and published a 2 year project to review these questions. This presentation will outline the committee’s findings, and the arguments supporting them.
