Overview: In this episode of EMRA*Cast, Dr. Jessie Werner and Dr. Jessica Whittle discuss high flow nasal cannula. Unsure of the difference among nasal cannula, a venti mask or a non-rebreather? Sick asthmatics? Pedi patients? Pneumonia? Learn when to use this modality to improve patient comfort and help stave off intubation.

Key Points:

Regular nasal cannula goes up to 15L/min but patients are really only getting about 6L/min because of outside air mixing in The progression of FiO2 goes nasal cannula🡪venti🡪non-rebreather High flow nasal cannula goes up to about 40L/min of flow and is humidified so it’s more comfortable for patients Evidence points to a mortality benefit using high flow nasal cannula in pneumonia patients
