Abstract
This study compared the thermal physiological and subjective responses of five subjects (1 female) to five hypothermia enclosure systems (HES) (with chemical heat sources) during 60 minutes of exposure to a -22°C climate. The five systems were: 1) user-assembled (Control); 2) Wiggy’s Victims Casualty Hypothermia Bag (W); 3) Doctor Down® Rescue Wrap® (DD); 4) MARSARS Hypothermia Stabilizer Bag (M); 5) Hypothermia Prevention and Management Kit (HPMK®). Total heat flux was significantly higher with the HPMK, W and M compared to the Control and DD (p<0.05). Net heat gain was higher with the Control and DD compared to W and M (p<0.05). Although all systems provide insulation and heat, the user-assembled and DD HES were more effective.
