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
Positive pressure means that air will flow from the high pressure area (surgical room) to the low pressure area (the corridors). This means airborne bacteria from the less sterile outside does not get carried into the more sterile surgical side by airflow.
Presumably the exhaust fan in your bathroom is designed to vent humid air from the bathroom to the outside – not quite the same intent.
