First Draft 3-15-97
Reflected Ceiling Plan Notes
Ambulatory Surgery Operating Room (General & Topical Anesthesia)
Note 1
Supply Air Outlet - Perforated 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 the HVAC Design Manual for Hospital Projects.
Note 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 the HVAC Design Manual
for Hospital Projects.
Note 3
Mounting Plate for Articulating Utility Column - (Do not scale.)
Size of mounting plate varies with
manufacturer. Exact size, type, and location are to be determined by the A/E in coordination with the VAMC
and Central Office program officials.
Note 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 the Electrical Design Manual, Chapter 6.
Note 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.
Note 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. For more information see Electrical SD F-27.
Note 7
General Illumination on Emergency Power - 50 percent of the fluorescent light fixtures above the operating
table are to be provided emergency power with battery backup. 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 provided emergency power. (See CS 800-3.) 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 put on emergency power.
Note 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 equipment shown is similar to that found in a cardiac cath procedure
room; however, the mounting plate for the video monitors is not to be supported on tracks due to asepsis
considerations.
Note 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.
Note 10
Sprinkler System - Coordinate the location of the sprinklers with other ceiling systems in accordance with
MCS, Division 15 and Plumbing Design Manual, Medical Centers.
Note 11 Provide no ceiling tracks for intravenous solutions in the design. This restriction is based upon concerns for
asepsis in the operating room.
