This is due to the greater heat transfer characteristics of Helium mix at depths where this mix is used. The tank of Helium mix would be full. It is not known at what temperature respiratory shock occurs in divers and it undoubtedly varies from diver to diver. Below that the diver's time underwater is shortened in direct proportion to the lowering temperature of inspired gas. This is a very dangerous situation.
Power is necessary to do the work of heating.
We believe that we have a potential solution to this problem in the works at Kirby Morgan Dive Systems and will publish the results when they are available. Careful observation and awareness by divers can help all of us understand how cold breathing gas affects us. All rights reserved.
