Abstract
The DCIEM Diving Manual, Helium-Oxygen Surface-Supplied Decompression Procedures and Tables, is a civilian version of the Mixed Gas Section of Chapter 3, Volume 3 of the Canadian Forces Diving Manual. It includes In-water Oxygen Decompression, Surface Decompression with Oxygen, Emergency Procedure Decompression and Abort Tables - in both feet of seawater (fsw) and metres of seawater (msw). The tables are designed for an 84% He/16% O2 breathing mixture. This gives a normal depth exposure limit of 300 fsw (90 msw) and an exceptional exposure limit of 330 fsw (100 msw). A higher percentage oxygen mixture can be used with these tables; however, the maximum depth possible will be reduced by oxygen toxicity considerations. A feature of these tables is the requirement for air decompression from the first stop to the 30 fsw (9 msw) in-water oxygen stop. The procedures parallel as much as possible those developed for the DCIEM air diving tables. Repetitive diving tables and diving at altitude are not addressed for these helium-oxygen tables. This manual forms Part 2 of the complete DCIEM Diving Manual.
