The aim of this pilot study is to evaluate if there is a dose-response relationship between the use of active external rewarming devices and core temperature rewarming rate from simulated accidental hypothermia. Volunteer research participants will be cooled in a field laboratory, and they will recieve medications to inhibit shivering, enabeling a drop in core temperature. Subsequently, they will be treated with either one, two or four heating blankets, and analyses will be performed to investigate whether we are able to find a difference between the three groups.

Volunteer research participants will be cooled in a field laboratory, and they will recieve medications to inhibit shivering, enabeling a drop in core temperature. All participants will be monitored extensively using a trans-nasal esophageal temperature probe, ECG, SpO2, Blood pressure, skin temperature and with subjective scores. After the cooling phase, the participants will be treated with either one, two or four heating blankets assigned in a randomized order, and analyses will be performed to investigate whether we are able to find a difference between the three groups.
