Core Rewarming

A technique used for patients with moderate/severe hypothermia
Without circulatory collapse Warm airways with heated, humidified air by O2 mask or endotracheal tube, eliminating respiratory heat loss, and increase body temperature by 1º–2ºC/hour; expand volume with warmed (40º–42ºC) IV solutions; other methods include peritoneal lavage with heated dialysate or closed pleural irrigation with warm saline
With hemodynamic instability Cardiopulmonary bypass; advantages include ability to maintain perfusion and oxygenation while rapid rewarming occurs and myocardial function recovers

They should be carried to shelter, and have active core rewarming using items such as heat packs or warm-water bottles, warm carbohydrate-containing fluids, and warmed blankets.
This includes advanced airway management, vascular access (intraosseous access may be easiest in very cold patients), warm intravenous fluids, core rewarming and cardiopulmonary resuscitation (CPR).
Core rewarming efforts should be continued when patients present to hospital.
