Brief summary
The purpose of this study is to compare two novel active rewarming techniques in mildly hypothermic people. Volunteers will undergo 3 cooling trials in a circulating bath at 14 degrees celsius and will then be rewarmed with either shivering alone, warmed iv fluids (IVF), or water perfusion pads applied to the hands and feet. The investigators hypothesize that both heated IVF and water perfusion pads to the arteriovenous anastomoses (AVAs) will prove to provide significantly superior rewarming rates than shivering alone.
Interventions
OTHERWarmed IV fluids
1 Liter of warmed IV fluids at 42 degrees celsius
OTHERWarmed perfusion pads
Neoprene perfusion pads placed on the palms and soles to rewarm through focusing on the arteriovenous anastomoses
