[摘要] 经鼻高流量氧疗(high-flow nasal oxygen,HFNO)是一种新型的氧疗技术,近年来开始逐步在临床普及应用。经过临床研究的不断探索,发现HFNO相较于传统氧疗具有诸多优势,并且在部分呼吸衰竭患者中的应用效果与无创通气相似,这为呼吸衰竭患者的呼吸支持提供了新的
The efficacy of high flow nasal canula oxygen therapy (HFNO) to prevent invasive mechanical ventilation (IMV) is not well established in severe coronavirus disease 2019 (COVID-19). The aim of this study was to compare the risk of IMV between two strategies of oxygenation (conventional oxygenatio...

In the recent years, High-Flow through Nasal Cannula (HFNC) has been introduced in the clinical practice. HFNC delivers to the patient heated humidified air-oxygen mixture, with an inspiratory fraction of oxygen (FiO2) ranging from 21 to 100% and a flow up to 60 L/min through a large...

High-flow nasal oxygen cannula( HFNC) has several features such as delivering heated and humidified oxygen,providing a stable oxygen concentration,flushing CO_2 from the nasopharyngeal cavity,creating a continuous positive airway pressure and so on. It is an easy and effective way to correct ...
flow nasal cannula therapy, FiO2 delivery is directly tied to flow rate. For increased FiO2, the rate must be increased. The low-flow nasal cannula is an open system of supplementation with high levels of leaking air around the oxygen source. As such, the efficacy of treatment for the low...
