湿化与未湿化对中低流量鼻导管吸氧过程中氧气湿度的影响

摘要

目的 探讨湿化与未湿化对中低流量鼻导管吸氧过程中氧气湿度的影响.方法 将接受持续中低流量鼻导管吸氧≥12 h的患者160例随机分为湿化组和未湿化组各80例,观察比较2组湿化瓶内的氧气湿度变化,同时监测室内湿度,观察湿化与未湿化对中低流量鼻导管吸氧过程中氧气湿度的影响.结果 2组湿化瓶内的氧气湿度比较无显著差异.结论 中低流量鼻导管吸氧无需常规湿化.%Objective To discuss influence of the humidification or non-humidification on oxygen humidity during low-mid volume oxygen inhalation through nasal cannula.Methods A total of 160 patients with low-mid volume oxygen inhalation through nasal cannula for≥12 hours were randomly assigned to the humidified group and the un-humidified group with 80 patients in each.Recording the chases of oxygen humidity from the humidifying bottles.at the same time the indoor air humidity was also observed.Influence of the humidification or non-humidification on oxygen humidity during low-mid volume oxygen inhalation through nasal cannula was observed.Results There was not significant difference in oxygen humidity between the two groups.Conclusions Routine humidifying is not necessary in low-mid volume oxygen inhalation through nasal cannula.
