True or false: Negative pressure airborne isolation rooms have exhaust that does not recirculate.

Negative pressure airborne isolation rooms are designed to contain airborne pathogens and prevent them from escaping into the surrounding areas. One of the key characteristics of these rooms is that they have a dedicated exhaust system. The air within these rooms is drawn in from adjacent areas, creating negative pressure that keeps contaminants contained. This air is then exhausted outside and is not recirculated back into the general ventilation system of the healthcare facility.

This design is crucial for infection control, as any potential pathogens present in the air are expelled from the building, thereby minimizing the risk of transmission to other patients, staff, or visitors. In summary, the fact that the exhaust does not recirculate is fundamental to the effectiveness of negative pressure isolation rooms, making the statement true.
