On surgical floors Operating Rooms(ORs) have positive pressure checks daily to ensure air handlers are working effectively. Why is positive pressure more desirable for surgery vs. negative pressure? Can either be compared to the exhaust fan in my bathroom on a smaller scale? Thanks!
In: Engineering
(Not medical a professional) air flows from positive to negative pressure. having positive pressure in an OR is a good thing given that when you open the door the air flows out of the room instead of into the OR. (potentially dragging bacteria whit it )
regarding your bathroom fan, not directly it’s main purpose is to create air circulation or more directly to drag the moist air out
