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!

Think of a room submerged under water, with a hole in the side. If it has negative pressure in the room, that means water is getting sucked in. If it has positive pressure, it is pushing air out.
Now replace that water with air. Some rooms don’t want air coming inside, as it could infect things inside the room. Some rooms don’t want air being pushed out, as it could infect everything outside it.
