<unk><unk> <unk> -flow (HHHF)<unk> , often also<unk> <unk>  nasal cannula(e) (HFNC) or<unk> <unk>  nasal oxygen (HFNO), is a type of respiratory support method that delivers a<unk> <unk>  (liters per minute) of medical gas to a patient through an interface (nasal cannulae) intended to create a wash-out of the upper airway. The applied gas is<unk>  to best match human body temperature (37 °C) and<unk>  targeting ideal body saturation vapor pressure. It is used in acute and chronic breathing problems, and is a suitable choice for treatment of patients with severe or critical COVID-19. A relevant parameter is the fraction of inspired oxygen (FiO2).
