An isolation room in a hospital where patients with infectious illnesses or patients who are susceptible to getting infections are kept away from other patients, visitors, and healthcare staff. These rooms are negatively pressurised in relation to the outside corridor and adjacent rooms.
The lower air pressure in a negative pressure room sucks in clean air from areas at higher pressure outside the room and helps prevent any infectious particles from traveling in the reverse direction. In a negative pressure room, the dirty air is sent out into the open air through mechanical exhaust devices.
