Did the FF/EMT factor in the non-linear response of the body to prolonged cold exposure in a semi-conscious state, or was the 2-hour hypothermic window derived purely from a calculated assumption of metabolic shutdown under idealized conditions?

Given the reported risk of imminent hypothermic death, can we assume the field intervention included a comprehensive thermal balance assessment prior to transport? Specifically, was there any attempt to implement active rewarming protocols during the extrication phase, or was the focus solely on stabilization and preservation of core temperature via passive methods?
