System Overview
Calibration GasesCalibration Gases
The two-point tonometered calibration of the CDI Shunt Sensors requires the use
of precision mixtures of carbon dioxide (CO
2
) and O
2
gas to expose the sensors to
well dened pH, pO
2
and pCO
2
values. A set of gas bottles provides enough gas for
approximately 30 individual sensor calibration procedures.
Gas 1 (CDI Model CDI746): Gas 2 (CDI Model CDI747):
CO2: 7.5 +/- 0.1% CO2: 2.8 +/- 0.1%
O2: 24 +/- 0.2% O2: 4.0 +/- 0.2%

Warning
 CONTAINS GAS UNDER PRESSURE; MAY EXPLODE IF HEATED.
 PROTECT FROM SUNLIGHT. STORE IN A WELL-VENTILATED
PLACE
Caution
 Check the expiration date on the gas bottles before use. Use of
the calibration gas bottles after expiration may result in inaccurate
calibration.
CDI Shunt SensorCDI Shunt Sensor
The CDI Shunt Sensors contain the K
+
, pO
2
, pCO
2
and pH
uorescent microsensors, as well as the thermistor contact
site for temperature measurement. The sensors are single use,
nontoxic and non-pyrogenic.
The heparin-coated, sterile CDI Shunt Sensors, Model
CDI510H, are intended for placement into shunt lines, purge
lines, sampling lines, shunt bypass lines or any similar line that
has blood ow. A minimum ow requirement of 35 mL/min is
necessary for proper measurement.
The disk-like lter/sparger on the sensor ensures a sterile
barrier when the sensor is placed into the Calibrator. The
sparger on the lter is located inside the sensor.
Do not remove this lter/sparger until placing the sensor into
the circuit.
