PLANNING AND DESIGN CONSIDERATIONS
A. Departmental net-to-gross factor (DNTG) for Electroencephalography Laboratory
is 1.50. This number when multiplied by the programmed net square foot (NSF) area
determines the departmental gross square feet.
B. This chapter applies specifically to equipment and facilities in a fixed location visited
by patients. It does not include facilities of a portable nature for transporting to the
patient or as used in neurological surgery.
C. Locate the Electroencephalography Laboratory contiguous with or within a neurology
nursing unit.
D. Isolate the Electroencephalography Laboratory from elevators, transformers, motors,
and wiring carrying large amounts of current. Voltage, particularly, will impact the
readings if allowed.
E. Environmental conditions must be stable since changes in such may be perceptible to
patients and may thus create physical responses which impact readings.
Temperature and relative humidity must be balanced to prohibit static electrical
charges at all times.
F. Provide electronic grounding in the exam rooms and workrooms to prevent
interference with the accuracy of the procedure.
G. Acoustically isolate exam rooms to inhibit distracting stimuli which will alter the
readings.
H. The EEG Control Room must be adjacent to the EEG Exam Room(s), and there shall
be a one-way mirror in the wall between each exam room and the control room. The
patient bed(s) shall be placed parallel to the mirror(s). Provide immediate,
unobstructed access from the control room to each exam room.
I.
Doors into patient treatment and exam rooms shall be 48" wide.
J. Configure patient waiting areas to provide clustered seating in order to eliminate large
waiting spaces, reduce noise and confusion, and improve the general patient
environment. Patient confidentiality should be maintained when providing personal
information to interview clerks and/or other staff.
K. Create clinic modules with connecting corridors to allow internal circulation of patients
and staff, avoid crossing public circulation patterns to the greatest extent possible.
L. Locate staff areas to be convenient to staff but separate from patient areas.
