Health Care - Isolation Rooms, Surgical Suites & Clean Areas
Examples of how CFD may be used to evaluate air quality, pathogen control, barrier containment and ventilation performance of health care related facilities.
Tuberculosis Isolation Suite
Analysis of an isolation area of a hospital showing black streaklines from the face of a patient (person not shown)and red streaklines from a ceiling supply diffuser. The objective of this study was to promote a one-way flow from the supply, to the patient, then to the exhaust. Both a bathroom and an ante room are attached to the TB room with special attention focused on airflow currents. The concentration of airborne particulates and bio-aerosols could have also been evaluated here.
Analysis of a hospital isolation area for immuno-compromised patients from treatments such as bone marrow transplants or chemotherapy. The streaklines show a continuous stream of fresh air reaching the patient without recirculation from contamination sources to their breathing zone.
