Title: Heat loss and tolerance time during cold exposure in heliox atmosphere at 16 ATA
Author: Brubakk, AO; Tonjum, S; Holand, B; Peterson, RE; Hamilton Jr, RW; Morild, E; Onarheim, J
Abstract: Four different types of protective clothing and three different methods of heat conservation protection were evaluated during an exposure to 4 degrees C cold in a heliox atmosphere at 150 msw. The divers using protective systems with little insulation had to quit the test after 1-2 h due to uncontrollable shivering and an extreme feeling of cold, whereas the divers using the heavily insulated clothing were able to stay in the chamber for 8-10 h. However, even with adequate protection against convective heat loss from the skin, respiratory convective heat loss will be high unless inspired gas is heated. This can be adequately done by using a combined heat-exchanger and scrubber where the heat produced by CO2 absorption is used to warm the inspired gas.
