Pulmonary barotrauma after a free dive--a possible mechanism

Aviat Space Environ Med. 1993 Mar;64(3 Pt 1):236-7.


Pulmonary barotrauma during scuba diving is a life-threatening event. In a skin diver, who does not use compressed air, this complication is rare and its pathophysiology is not readily understood. We present a young, healthy skin diver who suffered pneumomediastinum and subcutaneous emphysema after a sequence of free dives to 5 m, and suggest a possible mechanism.
