Calibrator mounting hook.
Fits onto the monitor pole clamp for optional
mounting on the CDI Model CDI517 Pole Clamp.

Calibrator cable guide.
Allows wrapping of the calibrator cable when not in
use.
Calibration gases
The two-point tonometered calibration of the CDI Shunt Sensors requires the use of
precision mixtures of CO
2
and O
2
gas in order to expose the sensors to well-defined
pH, PCO
2
, and PO
2
values. The set of gas bottles shall provide enough gas for ap-
proximately 80 individual sensor calibration procedures.
Gas A (Terumo CDI Model CDI506): Gas B (Terumo CDI Model CDI507):
CO
2
: 7.5 +/- 0.1% CO
2
: 2.8 +/- 0.1%
O
2
: 27.5 +/- 0.1% O
2
: 4.0 +/- 0.1%
N

: Balance N

: Balance
Warning
• The contents of the gas bottles are under pressure. Protect them from
sunlight, and do not expose them to temperatures exceeding 50°C
(122°F). Do not pierce or burn them, even after use. Do not spray the
contents of the gas bottles on a naked flame or any incandescent
material.
Caution
• Check the expiration date on the gas bottles before use. Use of the
calibration gas bottles after expiration may result in inaccurate calibration.
Terumo CDI Shunt Sensor
The CDI Shunt Sensors contain the K
+
, PO
2
, PCO
2
, and pH fluorescent microsen-
sors, as well as the thermistor contact site for
temperature measurement. The sensors are
single use, non-toxic, and non-pyrogenic.
The heparin-coated, sterile CDI Shunt Sen-
sors, Model CDI510H, are intended for place-
ment into shunt lines, purge lines, sampling
lines, shunt bypass lines, or any similar line
that has blood flow. A minimum flow require-
ment of 35 ml/min is necessary for proper
measurement.
The filter/sparger found on one end of the
sensor ensures a sterile barrier when the
sensor is placed into the calibrator.
The sparger on the filter is located inside the
sensor. Don’t remove this filter/sparger until
you are ready to place the sensor into the
circuit.
