Oxygen toxic seizures during hyperbaric oxygen therapy.

144,000 hits on Google for the two words “bleomycin” and “scuba” demonstrate the continued interest in the subject of diving after bleomycin therapy; some very conservative, and some more liberal regarding recommendations. My thanks to UHM, which published “Scuba diving post-bleomycin therapy” (UHM 2010, Vol. 37, No. 6, p. 455), documenting a recreational diver’s return to scuba after his chemotherapy with bleomycin. The article focused on objective evidence in the form of pulmonary function tests, and I wanted to update that information with another set of data points, as recorded in the accompanying table, eight years after chemotherapy and five years after returning to depths of 90 feet. Since 2010 the now 61-year-old index diver has done an additional 154 dives ranging from 37 to 137 feet (average 63 feet), all on air (no nitrox). I again call on the medical community to perform large-scale studies to develop parameters that would allow divers to safely return to scuba post-bleomycin therapy.
