Abstract
dDuring the severe acute respiratory syndrome coronavirus-1 epidemic, healthcare workers involved in aerosol-generating procedures, such as tracheal intubation or bronchoalveolar lavage, were at increased risk of becoming infected.1 For the current coronavirus disease 2019 pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), several international guideline committees have recommended that these procedures be performed in airborne isolation rooms.2e4 These rooms typically have a negative pressure relative to the adjacent hallway and a relatively high air exchange rate. However, because they are limited in most hospitals, it is inevitable that, in the context of a pandemic, aerosol-generating procedures in SARS-CoV-2-infected patients take place in other hospital environments, such as operating theatres or general ward rooms.
