Forced-air warming is promising for use during transport of cold patients. However, the current soft covers may be easily damaged in the nonhospital environment. Two rigid covers were designed to direct heat to the torso and thighs. Five subjects (one female) were heated with an AC powered heater (Bair Hugger 505, Augustine) and either a soft cover or the rigid covers (with heat input at the head or abdomen). Compared to the soft cover, the rigid cover (with heat input at the abdomen) provided similar heat delivery but a higher mean skin temperature. We conclude that the portable rigid covers are efficient for treatment of cold victims during pre-hospital transport.
强制空气加温法在运送体温过低的患者过程中很有应用前景。然而，目前的软覆盖物在非医院环境中可能很容易损坏。设计了两种硬质覆盖物，以便将热量导向躯干和大腿。五名受试者（一名女性）使用交流电加热器（奥古斯汀公司的Bair Hugger 505）进行加热，分别使用软覆盖物或硬质覆盖物（在头部或腹部输入热量）。与软覆盖物相比，硬质覆盖物（在腹部输入热量）提供了相似的热量传递，但平均皮肤温度更高。我们得出结论，便携式硬质覆盖物在院前转运过程中对低温患者的治疗是有效的。
