Respiratory support is applied to maintain adequateoxygenation and ventilation and hence supplementaloxygenation is the first line of treatment for hypoxemicrespiratory failure. There are multiple conventional oxygensupport devices. However, in majority of these, oxygenprovided is not humidified and maximum flow rate is 15l/min.However, high flow nasal oxygen (HFNO) is an alternative toconventional oxygen therapy. It is a technique that deliversheated and humidified oxygen with a controlled fraction ofinspired oxygen(FiO2) at a maximum flow rate of 60L/min via(1) a specialized nasal cannula
