Aerosol precautions are required when performing aerosol-generating procedures. These include taking respiratory tract samples for SARS-CoV-2 testing (such as nasopharyngeal and oropharyngeal swabs), intubation, bronchoscopy, open suctioning of the respiratory tract, and cardiopulmonary resuscitation.
Aerosol precautions for healthcare workers:
Healthcare worker PPE consists of gloves, gown (or apron), a fit-tested particulate respirator (N95 respirator or equivalent), and eye protection (goggles or face shield)
Use an adequately ventilated single room when performing aerosol-generating procedures, with spacing between beds of at least 1-1.5 metres.
