PPE gowns should be fashioned from a fabric that has been tested for its resistance to blood, body fluids and blood borne pathogens. A disposable, waterproof gown that covers the entire body is the recommended garment for medical practitioners. Aprons should only be used in cases where contamination is limited and are not advised for handling coronavirus patients.
Non-surgical isolation gowns have ANSI/AAMI PB70 Level 1 and 2 barrier protection. These may be used for surgery or invasive procedures with a low contamination risk. Surgical gowns (or, surgical isolation gowns) have ANSI/AAMI PB70 Level 3 and 4 barrier protection and should be used for surgery/invasive procedures with a medium to high risk of contamination.
Guidance for gowns suggests that non-surgical isolation gowns be used for routine care of patients with suspected COVID-19. The WHO recommends PPE gowns for both AGPs and non-AGPs in all situations except for initial triage. The gown should be clean, non-sterile and feature long sleeves.
