High flow nasal cannula (HFNC) systems allow us to deliver warm, humidified oxygen at flow rates as high as 60 liters/min through small, pliable nasal prongs. The cannula itself is fit into the nares and stabilized with a head strap. Two parameters are set – the flow rate and FiO2. Due to the high flow rates, much of the anatomic dead space (especially in the upper airways) is “washed out” improving the efficiency of oxygenation/ventilation. With the mouth closed, HFNC at 60 L/m can generate ~7 cm H2O of positive end expiratory pressure (PEEP) which helps decrease the work of breathing and also improves oxygenation.
