Schematic of nasal high flow therapy with arrows indicating the flow direction of delivered gas (air or air/oxygen mixture). (Arrow 1) Flow of gas provided by the NHF machine (constant). (Arrow 2) Flow of gas that exits the nasal cannula prongs into the patient’s nostrils. (Arrow 3) Cyclic flow of gas entrained by the patient during inspiration, or expelled during expiration, occurring around the nasal cannula prongs. NHF nasal high flow
