Practical strategies for aerosol drug delivery to sub-intensive patients with COVID-19.

1. Due to a limited number of ventilators available at hospitals, consider using HFNC for aerosol drug delivery to patients with asthma and COPD before they develop severe hypoxemic respiratory failure.

2. Place surgical masks on the face of infected patients during aerosol drug delivery through HFNC.

3. Administer aerosol therapy in negative pressure rooms.

4. Wear personal protective equipment, including an N95 respirator, goggles/face shield, double gloves, gown or apron if the gown is not fluid resistant.
