LEDs
Light Emitting Diodes.
Mean (average)
The numerical average of all the values in a data set. The mean is calculated as
the sum of the values in the set divided by the number of values in the set.
Message bar
The area above the parameter display window that’s used to convey current sys-
tem status and alarms.
Microsensors
Located on the sensor body, these are small dots of fluorescent chemicals which
emit light in response to flashes of light from the LED’s, correlating to the amount
of substrate present.
Navigation/input keys
The keys located at the bottom of the monitor’s front panel. They include the
+ (Plus), − (Minus), √ (OK), X (Cancel), and , , , and (left-, right-, up- and
down-arrow) keys.

Non-pyrogenic
Not fever-producing.
Operate mode toggle key
The key you press during operate mode to switch among the three types of dis-
plays — Numeric, Tabular, and Graphic. (This key is near the lower-right corner
of the monitor’s front panel.)
Optical Interface Material
A transparent material found on the back side of the Terumo CVS CDI Model
CDI510H Shunt Sensor. This material provides a means of consistent optical
connection between the sensor and the fiberoptic cable connector. The transpar-
ent optical interface material reduces the risk of measurement errors caused by
moisture or air trapped between the microsensors and the fiber optics.
Oxygen Delivery (
Ḋ
O

)
The amount of oxygen delivered to the patient during CPB expressed in ml per
minute.
Oxygen saturation
The amount of oxygen bound to hemoglobin in the blood, expressed as a per-
centage of the maximal binding capacity.
