title: A diving fatality due to oxygen toxicity during a "technical" dive.
abstract: An experienced diver drowned after a generalised seizure caused by oxygen toxicity during a 19-minute "technical" dive to a depth of 47 m. He had used a 50% oxygen/nitrogen gas mixture inappropriately during the dive. This case attests the risk of oxygen toxicity from oxygen-enriched air during deep dives, the shortcomings of the diver's equipment, and the need to examine, with knowledge of diving physiology and practice, both the body and equipment.
