High-flow nasal cannula oxygen therapy (HFNCOT) system consists of an air/oxygen supply capable delivering up to 100% humidified and heated at a flow rate 80 L/min. The includes blender, active humidifier, single tube, cannula. HFNCOT has many physiological advantages compared with other standard therapies, such as anatomical dead space washout, more constant fraction inspired oxygen, positive end-expiratory (PEEP) effect, supplement adequate humidification maintenance muco-ciliary function. is mostly used for hypoxemic acute respiratory failure, although it also indications. common choice physicians its technology makes silent comfortable. Though in clinical settings, there lack publications addressing devices initial settings. We present review on HFNCOT, focus device application methodology.
