新型氧气湿化输送系统的研制与临床应用

目的 保证氧疗效果,解决氧气湿化过程中普遍存在的湿化液污染及湿化产生噪声问题.方法 将172例需吸氧的肺癌患者随机分为观察组和对照组各86例,观察组应用自行研制的新型氧气温化输送系统吸氧,对照组使用传统氧气湿化输送系统吸氧.结果 观察组仅1例患者主观感受到湿化噪声,与对照组比较,差异有统计学意义(P<0.01);观察组湿化单元细菌培养阳性率显著低于对照组(P<0.01).结论 新型氧气湿化输送系统应用于临床氧疗,能降低传统氧气湿化液污染导致的医院呼吸道感染的风险,降低噪声,可保证患者休息,且不影响氧疗效果.

Clinical Application of New Humidified-oxygen-transfer System

Objective To solve the problem of fluid contamination and noise production during oxygen humidification.Methods A total of 172 patients were equally divided into a control group and an observation group.The observation group employed a newly invented device to humidify oxygen before inhalation,while the control group used a traditional method for humidification.Results The percentage of patients who complained of noises during oxygen inhalation in both groups had significant difference(P<0.01).Rate of posit...
