Abstract : A decompression table was developed to provide safe, efficient decompression from exposures of 40 feet for 720 minutes to 300 feet for 180 minutes at suitable increments of depth. On the basis of the results of 46 long exposure dives it was determined that control of such slower half-time tissues as the 160 and 240 minute tissues was required to provide reasonably safe decompression. The control of the allowable tissue tensions at the decompression stops was determined on the basis of the relation of change (S) and differential (E) to known safe tissue tensions at 66 feet and 33 feet absolute for the various half-time tissues. Decompression time required for long exposures calculated on these controls is much greater than provided by the present Air Saturation Table. The tables presented provide safe decompression for all but subjects more susceptible than usual to decompression sickness from long exposures. (Author)
