EMRA*Cast Episodes
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

Taking to the Sky: Launching an EM Resident Flight Physician Program
Resident involvement in air medical transport leads to significant mutual benefit for residents, residency programs, and flight programs. Residents gain unique clinical experiences and broaden their understanding of AMT and diversity of care settings. Residency programs benefit from the experiences of their residents. Flight programs gain enthusiastic and knowledgeable groups of new physicians who can augment the organization’s educational and clinical capabilities. Starting a resident flight program requires careful planning and significant coordination of stakeholders, but the result is an outstanding clinical experience for clinicians and patients alike.
