Abstract
For decades, the Wind Chill Temperature Index (WCT) and its various iterations have been used to assess the risk of frostbite on unclothed body parts. This paper presents an innovative knowledge-based Cold Weather Ensemble Decision Aid (CoWEDA) that can be used to guide the selection of the most appropriate cold weather ensemble(s) relative to anticipated mission physical activities and environmental conditions. CoWEDA consists of a validated six-cylinder thermoregulatory model, a database of clothing properties, algorithms for calculating the whole ensemble properties from individual garments and a graphical user interface. The user-friendly CoWEDA allows users to select from an inventory of clothing items to build an ensemble suitable for their needs. CoWEDA predicts the risks of both frostbite and hypothermia and ensures that a selected clothing ensemble will provide adequate protection to prevent cold injury. CoWEDA predictions provide not only estimates of frostbite risk similar to WCT tables but also hypothermia times and clothing required to prevent cold injuries. In addition, a CoWEDA model variant can predict survivability and clothing requirements during cold water immersion. Thus, CoWEDA represents a significant enhancement of the WCT-based guidance for cold weather safety and survival by providing greater individual fidelity in cold injury predictions.
期刊介绍:
The International Journal of Circumpolar Health is published by Taylor & Francis on behalf of the Circumpolar Health Research Network [CircHNet]. The journal follows the tradition initiated by its predecessor, Arctic Medical Research. The journal specializes in circumpolar health. It provides a forum for many disciplines, including the biomedical sciences, social sciences, and humanities as they relate to human health in high latitude environments. The journal has a particular interest in the health of indigenous peoples. It is a vehicle for dissemination and exchange of knowledge among researchers, policy makers, practitioners, and those they serve.
International Journal of Circumpolar Health welcomes Original Research Articles, Review Articles, Short Communications, Book Reviews, Dissertation Summaries, History and Biography, Clinical Case Reports, Public Health Practice, Conference and Workshop Reports, and Letters to the Editor.
