Some procedures performed on patients with known or suspected coronavirus disease 2019 (COVID-19) could generate infectious aerosols—in particular, procedures likely to induce coughing (eg, sputum induction, open suctioning of airways)—and therefore should be performed cautiously and avoided if possible. ^{1 2 3}

Healthcare professionals (HCPs) in the room should wear an N95 or higher-level respirator, eye protection, gloves, and a gown.

The number of HCPs present during the procedure should be limited to only those essential for patient care and procedure support. Visitors should not be present for the procedure.

Aerosol-generating procedures (AGPs) should ideally take place in an airborne infection isolation room (AIIR).

Clean and disinfect procedure room surfaces promptly. Information about recommended practices for terminal cleaning of rooms and personal protective equipment (PPE) to be worn by environmental services personnel is available in Healthcare Infection Prevention and Control FAQs for COVID-19.

Specimen collection should be performed in a normal examination room with the door closed.
