Modified bronchoscopy masks mitigate aerosols during gastroscopies (2022)
Working Paper
Phillips, F., Crowley, J., Warburton, S., Gordon, G. S., & Parra-Blanco, A. Modified bronchoscopy masks mitigate aerosols during gastroscopies

Digestive endoscopy has been proven to produce aerosols (1–3). This represents a risk of infection by COVID-19 and other airborne viruses. A number of protective barriers have been proposed to minimise that risk. Continuous suction of the oral cavity... Read More about Modified bronchoscopy masks mitigate aerosols during gastroscopies.
