传统吸氧方式是通过湿化液湿化吸氧,以减轻干燥的氧气对呼吸道黏膜的刺激,使患者感觉舒适。但氧气的物理特性是不易溶于水,尚无循证依据证实不同流量的氧气经过湿化液后能达到湿化效果,美国呼吸道管理协会在2002年关于氧疗的指导中提出氧气流量<4 L/min的鼻导管吸氧不必湿化。有研究[1]认为,中低流量鼻导管吸
The traditional method of oxygen inhalation is wetted by wetting oxygen to reduce the irritation of respiratory mucosa by dry oxygen and make the patients feel comfortable. However, the physical characteristics of oxygen are not easily soluble in water. There is no evidence based on the evidence that different flow rates of oxygen can reach the wetting effect after passing through the wetting solution. The American Society of Respiratory Tract Management suggested in 2002 that oxygen flow <4 L / min nasal catheter does not have to wet oxygen. Some studies [1] that the low-flow nasal catheter suction
