Isolation rooms with a switchable airflow rely on a mechanical air pressure management system that automatically alternates between positive and negative air pressures. These rooms are traditionally used for patients with immuno-compromised conditions. Therefore, positive pressure isolation prevents airborne pathogens from entering the room to avoid the air becoming contaminated. In a positive air pressure isolation room, the air pressure is higher than that in the adjoining areas. Exhaust mechanisms and systems suck contaminated air from the isolation room to a designated area. This system should also allow uncontaminated air to flow into the isolation room when the door is opened as air flows from a high to a low-pressure space. Used when caring for patients with highly infectious diseases, the isolation rooms are very effective. The negative air pressure prevents pathogens from flowing to adjoining, non-contaminated areas when the door to the room is opened. The air pressure in a negative air pressure isolation room is lower than the outside air pressure. Higher air pressures are positive, and lower air pressures are negative. In healthcare settings, isolation rooms have negative pressure, a positive pressure, or a switchable airflow.Įxperts continuously debate the efficacy of positive and negative pressure isolation rooms and how airborne infection isolation room pressures should be managed. Isolation rooms in hospitals can be classified according to the air pressure management system employed to contain the spread of pathogens. Air pressure stabilisers are used to maintain and manage these air pressure parameters.
