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.
- Regular nasal cannula goes up to 15L/min but patients are
really only getting about 6L/min because of outside air mixing
- The progression of FiO2 goes nasal
- 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
