[Decompression illness at low depth].

In this case report, a 38-year-old adipose male recreational diver was admitted to the accident and emergency de-part-ment with symptoms of decompression illness. The day before he had been diving at 3 m for approximately 1 h, and when a malfunction of the buoyancy control device occurred, he rapidly ascended, and symptoms began. The initial treatment was 10 l pure oxygen, which partially brought the symptoms to remission with full remission after undergoing hyperbaric oxygen therapy. This case shows, that decompression illness can occur at low depth, and time, activity, ascension and adiposity are risk factors.
