Core body temperature (Tc) in relation to time out of hospital and in hospital. Out-of-hospital rewarming with an active self-warming blanket (Mölnlycke^® BARRIER^® EasyWarm^®), in-hospital rewarming with Bair H Hugger™. Epitympanic Temperature may be underestimated because of low ambient temperature (− 8 °C) [33, 34]
