Problems of immersion.

1. All immersion casualties should be admitted to hospital for observation. If water has been inhaled and there are clinical signs in the chest they should be admitted to an ITU. 2. Attempts at resuscitation should always be made in apparently dead hypothermic immersion victims and only abandoned if unsuccessful after rewarming has occurred. 3. Always consider the possibility that an underlying pathological disturbance caused the incapacitation that led to the immersion incident. 4. If ventilatory support is required PEEP should be instituted as early as possible.
