Glossary and Acronyms
In vivo recalibration
Recalibrating the CDI OneView System during on-line operation so that its measured
values correlate more closely with those from the institution’s blood parameter
laboratory.
LEDs
Light Emitting Diodes.
Mean
A numerical average calculated as the sum of all values in the set divided by the number
of values in the set.
Microsensors
Small dots of uorescent chemicals on the sensor body that emit light in response to
ashes of light from the LEDs correlating to the amount of substrate present.
Non-pyrogenic
Not fever-producing.
Nontoxic
Not poisonous or productive of poison.
Optical interface material
A transparent material found on the back of the CDI Model CDI510H Shunt Sensor that
reduces the risk of measurement errors caused by moisture or air trapped between the
microsensors and the ber optics.
Oxygen consumption (VO
2
)
The amount of oxygen consumed by the tissues, expressed in mL O
2
/minute.
Oxygen delivery (DO
2
)
The amount of oxygen delivered to the patient during CPB, expressed in mL per minute.
Oxygen extraction ratio (O
2
ER)
The ratio of oxygen consumption (VO
2
) to oxygen delivery (DO
2
).
Oxygen Saturation (SO
2
)
The amount of oxygen bound to hemoglobin in the blood, expressed as a percentage
of the maximal binding capacity.
Potential of Hydrogen (pH)
The unit for measuring the degree of acidity or alkalinity of a substance as related to
its concentration of hydrogen ions.
