High-flow nasal cannula oxygen therapy (HFNCOT) system consists of an air/oxygen supply system capable of delivering up to 100% humidified and heated oxygen at a flow rate of up to 80 L/min. The system includes a blender, active humidifier, single heated tube, and nasal cannula. HFNCOT has many physiological advantages compared with other standard oxygen therapies, such as anatomical dead space washout, more constant fraction of inspired oxygen, positive end-expiratory (PEEP) effect, supplement of adequate humidification and maintenance of muco-ciliary function. HFNCOT is mostly used for hypoxemic acute respiratory failure, although it also has other indications. HFNCOT is a common choice of physicians as its technology makes it more silent and comfortable. Though HFNCOT is used in many clinical settings, there is a lack of publications addressing devices and initial settings. We present a review on HFNCOT, with focus on device and application methodology.
高流量鼻导管给氧治疗（HFNCOT）系统由一个空气/氧气供应系统组成，该系统能够以高达80升/分钟的流速输送高达100%的加湿和加热氧气。该系统包括一个混合器、主动加湿器、单根加热管和鼻导管。与其他标准氧疗相比，HFNCOT具有许多生理优势，如解剖无效腔冲洗、吸入氧分数更恒定、呼气末正压（PEEP）效应、充足加湿补充以及黏液纤毛功能维持。HFNCOT主要用于低氧性急性呼吸衰竭，不过它也有其他适应证。HFNCOT是医生的常用选择，因为其技术使其更安静、更舒适。尽管HFNCOT在许多临床环境中都有应用，但缺乏关于设备和初始设置的出版物。我们对HFNCOT进行综述，重点关注设备和应用方法。
