摘　　要：目的探讨在机械通气患者撤机过程中,使用单向活瓣通气给氧的方法对脱机训练的影响。方法选择行机械通气72 h以上患者48例,符合撤机标准,在准备撤机前将患者随机分成观察组和对照组各24例,观察组使用单向活瓣通气给氧的方法对患者进行脱机训练,对照组采用常规氧气管给氧通气的方法,通过观察两组患者的血气分析、呼吸频率、心率、血压变化,并了解患者的耐受性及舒适度改变等指标。结果两组患者在脱机后1 h3、h2、4 h动脉血气分析的血氧分压(PaO2)、动脉血氧饱和度(SaO2)、呼吸次数、心率、血压变化相比较,差异有显著性意义(P<0.05)。观察组患者的耐受性及舒适度明显比对照组好。结论使用单向活瓣通气给氧用于机械通气患者撤机的方法,可以使患者能吸入较精确的足够的氧混合气体,降低导管死腔,减少患者的呼吸做功,增加患者的舒适度,从而能使患者达到快速、顺利脱机的目的。Objective To study the one-way valve oxygen supplying method used in the course of training for weaning from mechanical ventilation. Method 48 cases of patients treated with mechanical ventilation for over 72 hours （all of which must conform to weaning from mechanical ventilation requirements） were selected and into two groups, the observation group and the control group, each containing 24 cases. Use one-way valve oxygen supply device on the observation group and regular oxygen supplying device for control group, the blood analyses, breathing rates, heart rates, blood pressure change, resistibility and comfort feeling change were measured and compared between the two groups. Result There is significant difference in blood oxygen partial pressure （PaO2）, artery blood oxygen concentration （PaO2）, breathing rates, heart rates, blood pressure changes between the two groups. The observation group has obviously better resistibility and comfort feeling than that of control group. Conclusion The weaning method by one-way valve oxygen supplying can ensure inhale an accurate amount of oxygen mixture, and lower the risk of duct blockage, decrease the work load during patient＇s breathing and improve the comfort feeling. Therefore, the patient can be accustomed to a rapid and safe weaning from mechanical ventilation .
