Notes:
1. Supply Air Outlet - Perforated stainless steel panel centered over operating table with no obstructions. A/E is to design it. (Do not scale.)
This outlet is to provide 30 percent of supply air for the operating room. Air distribution is to be in a downward vertical direction. See
HVAC Design Manual for Hospital Projects, PG-18-10.
2. Supply Air Outlets - Stainless steel multiple slot panel diffusers to be located above the perimeter of the "clean air zone". (See Functional
Plan.) A/E is to design them. (Do not scale.) These outlets are to provide 70 percent of supply air for the operating room. This air is to
be discharged in a vertical air stream inclined at an outward angle of fifteen degrees from the center of the room. See HVAC Design
Manual for Hospital Projects, PG-18-10.
3. Mounting Plate for Utility Column - (Do not scale.) Size of mounting plate varies with manufacturer. Exact type, size, type, and location
are to be determined by the A/E in coordination with the VAMC and Central Office program officials.
4. Surgical Light Fixture - Note that the location of the mounting plate is not to be placed directly over the operating table. That zone must be
kept unobstructed for the supply air outlet and the plenum serving it above the ceiling. See Electrical Design Manual for Hospital Projects,
PG-18-10.
5. Surgical Microscope - If VAMC chooses a ceiling-mounted microscope in lieu of a floor-mounted microscope, it must be supported by a
fixed mounting plate. A ceiling track-mounted system is not to be used for the microscope due to concerns regarding asepsis. The exact
size of the mounting plate depends upon the microscope selection. (Do not scale the guideplate.) Coordinate details and utilities
requirements with the VAMC.
6. Fluorescent Light Fixtures - General illumination. Only 2 x 4 recessed fixtures are to be used in the operating room due to the fact that
this size of fixture (with 6 lamps - Type D) is required in order to deliver enough ambient illumination while also producing color corrected
light in the operating room. The design is not to include 1 x 4 fluorescent fixtures. Each group of fixtures (a,b,c) shall be controlled by
switches (dimmers are not acceptable) so that 3 distinct levels of illumination are provided. For example, in the fixtures designated by "a,"
"b" and "c," the (2) outside lamps shall be controlled by one switch; the (4) inside lamps shall be controlled by a second switch.
7. General Illumination on Emergency Power - 50 percent of the fluorescent light fixtures above the operating table are to be on emergency
power with battery backup (Type D1). The fluorescent fixtures above the head of the patient (where the nurse anesthetist administers
anesthesia and monitors the patient's vital signs) are to be on emergency power. Since the "head of the table" may be reversed on
occasions when the ceiling-mounted microscope is in use, fluorescent fixtures above both ends of the table are to be on emergency
power.
8. Mounting Plate for Video Monitors - If the VAMC chooses a suspended video system instead of a cart-mounted system, the mounting
plate must be integrated into the ceiling layout. The exact size and location of this plate must be determined. The mounting plate for the
video monitors is not to be supported on tracks due to asepsis considerations.
9. Video Monitors - A proposal to be considered is to provide a fiber-optic connection (enclosed in conduit) from the video monitors in the
operating room to the microscope in the frozen section area of the clinical laboratory. This would permit the surgical team in the operating
room to see what the pathologist is talking about over the intercom while examining the biopsy specimen. This installation would reduce
the need for anatomical pathologist to leave a contaminated area. Also, the surgical team would not have to wait for the pathologist to
clean up, gown, and come to the operating suite to examine the tissue specimen.
10. Sprinkler System - Coordinate the location of the sprinklers with other ceiling systems in accordance with MCS, Division 15, Mechanical
and Plumbing Design Manual for Hospital Projects
11. Provide no ceiling tracks for intravenous solutions in the design. This restriction is based upon concerns for asepsis in the operating room.
