Glossary and Acronyms
pH-stat
Maintenance of a constant pH at 7.40 and pCO
2
at 40 mmHg, over varying temperatures,
accomplished by measuring blood gas values at actual patient temperature.
Partial Pressure of Carbon Dioxide (pCO
2
)
The pressure exerted by carbon dioxide gas in the blood.
Partial Pressure of Oxygen (pO
2
)
The pressure exerted by oxygen gas in the blood.
Potassium (K
+
)
The major cation of intercellular uid.
Q

Blood value accurate up to mL/min obtained manually, via Flow Sensors connected
through the Flow Interface Module or via supported pumps connected through the
HLM Interface Module.
Standard deviation (precision)
A measure of how spread out the values in a data set are.
SRS
Standard reference sensor.
Thermistor
A silver cap located on the BPM that measures the temperature of the blood when
connected to a sensor.
Tonometered
A measurement characteristic of the calibration gases used with the CDI OneView
System. The gas concentrations used with the CDI OneView System meet guaranteed
specications to ensure every gas bottle provides consistent calibration.
Two-point tonometered gas calibration
A calibration procedure that uses the supplied gas bottles to deliver a precise mixture
of CO
2
and O
2
gas in order to expose the sensors to well dened pH, pCO
2
and pO
2
values. The Core determines the intensities related to these specic points and draws a
slope and intercept value from them.
