Decompression Tables in Relation to Dysbaric Osteonecrosis.
The stresses of decompression and the possibility that dysbaric osteonecrosis is a form of decompression sickness with delayed manifestations were studied. Also considered was the possibility that fatty bone marrow may exchange gas very slowly and thus gradually become dangerously supersaturated after several successive dives. Two sets of maximum allowable inert-gas tissue tensions were used to calculate nitrogen tissue tensions at the start of a dive and at surfacing from five different decompression tables. Analysis suggested that the values given in the tables are reasonably safe. The qualification is that there must be a minimum surface interval of 12 hours between dives.
