Nasal Oxygen Delivery Devices
#criticalCare #pulmonary #oxygenation #ICUEquipment
Most people breathe through the nose, and it’s a common route for administering supplementary oxygen. This OnePager reviews nasal oxygen delivery devices, including conventional nasal cannula (NC), reservoir nasal cannula, and heated high-flow nasal cannula (HFNC). It also covers apneic oxygenation.

FLORALI Study, NEJM 2015 (in patients with hypoxemic respiratory failure, high flow nasal oxygen was associated with lower 90 day mortality)
Effect of Postextubation High-Flow Nasal Cannula vs Conventional Oxygen Therapy on Reintubation in Low-Risk Patients, JAMA 2016 (extubation to HFNC reduced reintubations)
The effects of flow on airway pressure during nasal high-flow oxygen therapy, Respiratory Care 2011 (there is a linear relationship between flow and pressure on HFNC; 0.7 cmH2O of PEEP for every 10 lpm of flow)
