2-2-2-3 Cooling
The cooling requirement for a console Ultrasound system with
monitor and on board peripherals, is up to 3800 BTU/h. This
figure does not include cooling needed for lights, people, or
other equipment in the room.
NOTE: Each person in the room places an additional 300 BTU/h
demand on the cooling system.
2-2-2-4 Lighting
Bright light is needed for Ultrasound system installation, updates
and repairs. However, operator and patient comfort may be
optimized if the room light is subdued and indirect. Therefore a
combination lighting system (dim/bright) is recommended. Keep
in mind that lighting controls and dimmers can be a source of
EMI which could degrade image quality. These controls should
be selected to minimize possible interference.
