Abstract
Decompression tables designed for use at sea level can not be used directly when diving at reduced atmospheric pressures. Altitude-corrected standard air decompression tables, oxygen decompression tables, and repetitive diving tables, based on the DCIEM 1983 decompression model, have been developed for the Canadian Forces School of Aeromedical Training (CFSAT) at Edmonton, Alberta. These tables can be used directly since they have been calculated for the elevation of Edmonton. Treatment tables, which are designed for use at sea level, also can not be used directly at altitude. An analysis of treatment tables shows that the standard treatment tables, if dived exactly with air only as the breathing gas, are unsafe for the inside attendant and that oxygen breathing towards the end of the tables is necessary to reduce the risk of decompression sickness.
