In patients with an artificial airway, inspired gases can be humidified and heated using a passive (heat and moisture exchange filter - HMEF), or an active system (heated humidifier).
To assess how humidification is carried out and what is the usual clinical practice in this field in Chilean intensive care units (ICUs).
A specific survey to evaluate humidification system features as well as caregivers' preferences regarding humidification systems, was carried out on the same day in all Chilean ICUs.
Fifty-five ICUs were contacted and 44 of them completed the survey. From a total of 367 patients, 254 (69%) required humidification because they were breathing through an artificial airway. A heated humidifier was employed only in 12 patients (5%). Forty-three ICUs (98%) used HMEF as their routine humidification system. In 52% of surveyed ICUs, heated humidifiers were not available.
In Chile the main method to humidify and heat inspired gases in patients with an artificial airway is the HMEF. Although there are clear indications for the use of heated humidifiers, they are seldom employed.
对于有人工气道的患者，可使用被动式（热湿交换过滤器 - HMEF）或主动式系统（加热湿化器）对吸入气体进行湿化和加热。
评估智利重症监护病房（ICU）如何进行湿化以及该领域的常规临床实践情况。
在同一天对所有智利ICU进行了一项特定调查，以评估湿化系统特征以及护理人员对湿化系统的偏好。
联系了55个ICU，其中44个完成了调查。在总共367名患者中，254名（69%）因通过人工气道呼吸而需要湿化。仅12名患者（5%）使用了加热湿化器。43个ICU（98%）将HMEF作为其常规湿化系统。在52%的被调查ICU中，没有加热湿化器。
在智利，对有人工气道患者的吸入气体进行湿化和加热的主要方法是HMEF。尽管有明确的使用加热湿化器的指征，但很少使用。
