Abstract
The prediction of survival time for cold water immersion is very difficult due to several uncertainties. Foremost is the lack of well-documented data; hence the reliance of extrapolative techniques from controlled exposures involving mild levels of hypothermia. A second obstacle is the wide variability of individual response to cold. The challenge of prediction is further exacerbated by the ambiguity in the definition of survival time. These concerns must be addressed to improve the safety and rescue of people in the offshore environment. An international workshop was held to investigate the role of survival prediction models with a special emphasis on terminology. Following a review of prediction methods and models, assumptions were discussed, standard definitions were agreed upon, the extension to specific populations was noted, a standard clothing menu for modeling purposes was agreed upon, the collation of case histories and their use for model calibration and validation was discussed, and future directions were summarized. The primary recommendation was the adoption of the definition of survival time as the time for a body to cool to 28C. This definition purposely excludes the possibility of death by factors other than hypothermia such as drowning. TRUNCATED
