When discussing options for hypoxemia, there seem to be so many noninvasive oxygen delivery systems! Nasal cannula, high flow nasal cannula (HFNC), non-rebreathers (NRB), and more are routinely used in the settings I’ve worked in.
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.…
