I made this informational presentation for Covid-19. Includes all the info I thought was interesting. Sources are mostly the NEJM and JAMA articles everyone else has been looking at, along with some WHO info and pubmed searches. Feel free to share!
Edit: lancet has an article on airway management that recommends against HFNC and NIV.
“An experiment with a mannikin showed that NIV or HFNC, when well applied with an optimal fit, only lead to minimal dispersion of exhaled air. However, the specific NIV and HFNC models and modes tested in the study are not universally used across all hospitals. Therefore, to avoid confusion and potential harm, we do not recommend using NIV or HFNC until the patient is cleared of COVID-19. Airway devices providing 6 L/min or more of oxygen are considered high-flow5 and we discourage their use if an airborne infection isolation room is unavailable.”
