摘　　要： 目的探讨文丘里装置联合加温加湿器在Ⅱ型呼吸衰竭气管切开脱机患者中的应用。方法选择Ⅱ型呼吸衰竭气管切开脱机患者32例，随机分为观察组和对照组，每组16例。观察组应用文丘里装置联合加温湿化器加温湿化，湿化液为无菌注射用水；对照组采用常规湿化给氧方法，湿化液为0．45％氯化钠溶液。比较2组患者在治疗护理过程中吸入气体平均温度、气道湿化满意率和血气指标。结果观察组在气道湿化满意率、吸入气体平均温度、血气分析中PaO2和PaCO2平均值优于对照组，差异有统计学意义（P〈0．05或P〈0．01）。结论文丘里装置联合加温加湿器更适用于Ⅱ型呼吸衰竭气管切开脱机患者，可以减少CO2潴留，减少气道并发症，增加患者舒适度。 Objective To explore the application of ventnri devices combined with heating humidifiers in type Ⅱ re- spiratory failure patients after tracheotomy. Methods A total of 32 respiratory failure patients were enrolled after trache- otomy and randomly divided into an observation group and a control group （n = 16）. The observation group used venturi devices combined with heating humidifiers, where sterile water was used as the wetting fluid. Meanwhile, a conventional oxygen humidifying method was applied in control group, where 0. 45% normal saline was used as the wetting fluid, Then, the two groups were compared for the average temperature of inhaled gas, partial pressure of oxygen （ PaO2 ） and partial pressure of carbon dioxide （ PaCO2 ）. Results Compared with the control group, the observation group produced remarkable improvement in humidifying in the airway, the average temperature of inhaled gas, as well as PaO2 and PaCO2 （ P 〈 0.05 or P 〈 0. 01 ）. Conclusions The combined use of venturi devices and heating humidifiers is more suitable in treatment of type Ⅱ respiratory failure patients after tracheotomy, which can reduce CO2 retention, avoid airway compli- cations, and increase patient satisfaction.
