b. Any room (e.g. examination/treatment room procedure room) in the health care facility
in which aerosolized pentamidine (AP) procedures are performed on patients who may have infectious TB
must meet CDC guidelines for infectious TE with the additional requirement that a minimum of 12 air
changes per hour must be exhausted (See IV .A-2). Additionally, airflow rates should be calculated on
expected patient turnover in these treatment areas based on the most recent CDC guidance. If a booth or
other containment entity is used for any potential aerosol producing procedure, booth airflow and exhaust
should meet CDC guidelines.
K. Radiology
At least one radiology room with chest x-ray capabilities should meet CDC guidance for S/KI TB. Both
ambulatory care and in-patient programs can share this negative pressure radiology room if feasible.
This specialized room with these engineering controls may not be necessary in facilities in the minimal
risk category.
L. Anatomic Pathology:
The morgue must meet at a minimum CDC guidance for infectious TB and follow current VA criteria
with a minimum of 12 air changes per hour with 100% exhaust to the outside through a HEPA filter.
M. Dental
At referral centers and at facilities in which emergency dental care is provided, at least one dental
operators should meet CDC guidance for S/KI TB. Other health care Facilities may send S/KI TB
patients for dental. care to referral centers based on workload and travel distance.
N. HIV-related Issues
No, specific heating, ventilation and air conditioning (HVAC) considerations are necessary for patients
with HIV infection.
O. Dialysis Program
A room which meets at a minimum current CDC ventilation and airflow guidelines for S/KI TB must be
available for dialysis of S/KI TB patients. The location of this area is at the discretion of the facility.
Based on local need this area may be in the dialysis unit or ICU, or other area in the Medical Center
based on patient need and efficient use of resources.
V. Respiratory Protection
A. General Criteria
Performance criteria for respiratory protective devices as outlined in the most recent CDC guidance are to
be met. This requires a respiratory protection program that follows the regulatory requirements of the
Occupational Safety and Health Administration (OSHA) as well as American National Standards
Institute (AINSI) Standards.
