Level 1 gowns provide a minimal fluid barrier protection. They are used for standard precautions and simple procedures for example, during basic care, standard isolation, or in a standard medical unit.
Level 2 gowns provide minimal to low fluid barrier protection. They are used for minimally invasive surgery, during blood draw, suturing, in the Intensive Care Unit (ICU), or a pathology lab.
Level 3 gowns provide moderate fluid barrier protection. Level 3 gowns are used for the widest range of surgical procedures, where moderate fluid protection is necessary. Specifically, for arterial blood draw, inserting an Intravenous (IV) line, in the Emergency Room, or for trauma cases.
Level 4 gowns provide the highest fluid and microbial barrier protection against blood-borne pathogens in critical zones. They are needed for long, fluid-intensive procedures, surgery, when pathogen resistance is needed or infectious diseases are suspected (non-airborne)
