Temperature variations in different parts of three heat and moisture exchangers (HME) were measured during spontaneous breathing. Temperatures below ambient occurred in the distal part of two of them. The lowest temperatures recorded were more than 6 degrees C below room temperature. This effect can explain why gas expired through a good HME is not saturated with water at ambient temperature.
在自主呼吸过程中，对三个热湿交换器（HME）不同部位的温度变化进行了测量。其中两个热湿交换器的远端出现了低于环境温度的情况。记录到的最低温度比室温低6摄氏度以上。这种效应可以解释为什么通过性能良好的热湿交换器呼出的气体在环境温度下未被水饱和。
