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!

Positive pressure: Pressure is higher in the room, so that when the door is opened, air flows out. You put an immunocompromised person in here, so that nasties don’t get in.
Negative pressure: Pressure is slightly lower in this room, and air flows in when the door is opened. You put your Ebola patient in here, so that nasties don’t blow out into the hallway.
