Placing a mask on COVID-19 patients during high-flow nasal cannula therapy reduces aerosol particle dispersion

Wearing a surgical/procedure mask over high-flow nasal cannula (HFNC) reduces aerosol particle concentrations in the patients' vicinity. Wearing a mask over HFNC should be encouraged to reduce risks of aerosol transmission. #COVID19 https://bit.ly/2HLg5cE.
