In response to a request for technical assistance from the National Center for Infectious Diseases and the National Center for Prevention Services, Centers for Disease Control, an investigation was made of ventilation for the isolation of tuberculosis patients at the Veterans Administration Medical Center (SIC-8062), East Orange, New Jersey. Ventilation measurements were on an infectious disease ward (5B) housing acquired immune deficiency patients, to determine the status of the ventilation systems serving the area. Two single bed patient rooms were being used for isolation of tuberculosis patients at the time of the survey. The average supply airflow varied above and below the designed value. The rooms were all positively pressurized; this is not recommended for the isolation of infectious patients. Smoke tube traces were used to determine room to corridor pressure relationships, and the pressure relationship of this particular ward to the core areas of the hospital. There was found to be a general flow of air out of the ward into the core area. The air flowed through the core area and into an adjacent wing of the hospital, which could result in infectious agents being circulated to other wards and floors of the hospital due to the sharing of the ventilation systems. The authors conclude that there was no isolation of infectious patients on Ward 5B. The authors recommend that a separate isolation facility be constructed to house infectious patients.
