The use of heated humidification in adults does not appear to be an important factor in maintaining body temperature in adults. Heat and moisture losses certainly can be reduced with heated humidification, but the contribution to temperature regulation appears small. The use of an HME reduces heat loss form the respiratory tract, but this loss is minute compared with losses from the skin, fluid administration, and the operative site. In neonates, the use of heated humidification during surgery may help contribute to thermal balance owing to the unique issues of temperature regulation and control in these patients.
在成人中使用加热湿化似乎并非维持体温的重要因素。加热湿化确实可以减少热量和水分的流失，但对体温调节的作用似乎较小。使用热湿交换器（HME）可减少呼吸道的热量损失，但与皮肤、输液及手术部位的热量损失相比，这种损失微不足道。在新生儿中，由于这些患者体温调节和控制存在独特问题，手术期间使用加热湿化可能有助于维持热平衡。
