摘　　要：在机械通气治疗过程中，必须通过人工湿化来代替人上呼吸道的功能，良好的气道湿化是机械通气治疗过程中的重要环节。现阶段机械通气患者常用的气道湿化装置是加热湿化器和热湿交换器。本文介绍两种湿化装置的优缺点，并在湿化效果、对呼吸机使用的影响和与呼吸机相关性肺炎的关系这几方面对两者进行了比较。临床工作中要根据患者的实际情况选择湿化装置，并且根据患者的治疗效果随时进行调整。Humidificait on by artificial means must be provided when the upper airway is bypassed during mechanical ventilation.Enough humidification is very important during mechanical ventilation.Heated humidification（ HH） and heta and moisture exchanger（ HME） are the most commonly used types of artificial humidification in this situation.In this article, their advantages and disadvantages are itn roduced.HH na d HME are compared in humidification performance,effect no ventilator mechanics and association with venti-lation associated pneumonia.Depending on the clinical scenario, humidifier is reasonably selected, and the selection may changeo ver time according the treatment effect.
