Background High flow nasal cannula therapy (HFNC) may increase aerosol generation, putting healthcare workers at risk, including from SARS-CoV-2. Aim This study examined whether use of HFNC increases near-field aerosols and if there is a relationship with flow rate. Methods Subjects aged four weeks to 24 months were recruited. Each child received HFNC therapy at different flow rates. Three stations with particle counters were deployed to measure particle concentrations and dispersion in the room: station one within 0.5 m, station two at 2 m, and station three on the other side of the room. We measured carbon dioxide (CO2) and …
