Title: Placing a Mask on COVID-19 Patients during High-Flow Nasal Cannula Therapy Reduces Aerosol Particle Dispersion Cord-id: s5c4b83z Document date: 2020_10_30

Snippet: High-flow nasal cannula (HFNC) has been shown to improve oxygenation and reduce the need for intubation for hypoxemic patients [1]. A retrospective study reported the effectiveness of HFNC to improve oxygenation of COVID-19 patients [2]. The transmission route of the SARS-CoV-2 virus remains controversial [3, and concerns persist of potentially increased virus transmission when utilising HFNC among COVID-19 patients [3–5]. Computational fluid dynamic simulations reported that wearing a surgica

The transmission route of the SARS-CoV-2 virus remains controversial [3, and concerns persist of potentially increased virus transmission when utilising HFNC among COVID-19 patients [3–5]. Computational fluid dynamic simulations reported that wearing a surgical/procedure mask over HFNC may reduce aerosol droplet dispersion [6].
