CDI System 500
®
Blood Parameter Monitoring System
Continuous blood
parameter monitoring
for improved blood
gas management
The world's most trusted and used
continuous in-line blood gas monitor
For more than 15 years, the CDI® Blood Parameter Monitoring System 500 (CDI System 500) has been trusted and
used by the world’s leading cardiac hospitals to continuously measure and calculate vital blood parameters during
cardiopulmonary bypass. Terumo Cardiovascular Group proudly continues to serve our customers with the leading
technology available today.
Based on optical fluorescence and reflectance technologies, the CDI System 500 continuously measures or
calculates 11 critical blood parameter values, including: pH, pCO2, pO2, potassium (K +), oxygen saturation,
hematocrit, hemoglobin, and temperature.
The proven technology of the CDI System 500
Only the CDI System 500 shunt sensor
measures pH, pCO2 , pO2 , and potassium
Constant monitoring of the patient’s
changing condition
The CDI System 500 shunt sensor is designed to be placed
in a shunt line where the blood is in direct contact with the
system’s sterile microsensors. Accurate measurements
of these critical parameters provide clinicians with the
information to improve patient care:
Blood parameters can change rapidly during
cardiopulmonary bypass-supported procedures
due to a multitude of dynamic conditions. Blood
gas analyzers only reflect the patient’s clinical
condition for the exact moment the sample is
drawn. The blood sample results may not reflect
recent changes in blood gas parameters and
patient conditions.
• pH and pCO2 – to monitor for and classify metabolic
and respiratory alkalosis/acidosis
• pO2 – to more consistently control partial pressure
of oxygen, avoiding hyper/hypoxia
• pCO2 – to monitor for excessive or deficient levels
of carbon dioxide in the bloodstream, which could
result in hyper/hypocapnia
• Potassium (K+) – to quickly identify conditions
that may lead to hyper/hypokalemia
The CDI System 500 provides continuous
monitoring, and system alerts provide visual
and audible indicators when parameters
fall outside user-specified limits.
Quick recognition of fluctuations in
critical physiological parameters
The system’s average response time for measured
parameters (pH, pCO2, pO2 and K+) is in seconds.
These real-time system updates enable you to
identify undesirable trends quickly.

Monitor
• Modular probes allow user to
configure system to meet specific
monitoring requirements.
• Large, color LCD display provides high
visibility at a variety of viewing angles.
• Integrated battery pack ensures
uninterrupted operation for
25 minutes.
• Monitors blood/patient in either
actual or 37˚ C temperature
mode to allow for Alpha stat
or pH stat management.
• Displays blood parameter values
in either numeric, graphic, or
tabular formats.
Monitor Pole
Clamps
Available in two arm
lengths, 7 inches and
41/2 inches, that attach
to standard heart-lung
machine poles.
• Integral monitor printer provides
documentation of system’s selfdiagnostics and calibration verification,
as well as displayed values.
• RS-232 serial interfaces accept inputs
from pumping system to use and
display blood flow, and provide outputs
to data management systems or
transmission to other external devices.
• Built-in handle for transportability.
Calibrator
Shunt Sensor
H/S Cuvette
• Fast 2-point gas calibration assures shunt
sensor is performing to specifications.
• Unique fluorescence sensor technology
measures pH, pCO2, pO2, and K +.
• Optical reflectance technology provides
accurate readings of venous SO2 /Hct/Hgb.
• Small footprint and built-in handle for
transportability.
• Simple installation of the sensor into the shunt
line using luer connections.
• Disposable cuvette clips easily to
hematocrit/saturation probe.
• Mountable onto monitor pole clamp.
• May also be added after the initiation of bypass,
facilitating set up in emergency cases.
• Available in three connector sizes: 1/4 x 1/4,
3⁄8 x 3⁄8, and 1/2 x 1/2 inches.
Cable Head

The CDI® System 500 quickly alerts
you to changes in patient status
Continuous in-line monitoring during cardiopulmonary bypass surgery is a critical
component of perfusion safety and improving patient outcomes. Studies have shown
that appropriate regulation of blood gas parameters is essential to avoid the negative
outcomes linked to sub-optimal blood gas parameter control. More precise and
accurate control of blood gas parameters could potentially improve:
• Cardiac function
• Transfusion requirements
• Renal function
• Ventilator requirements
• Pulmonary function
• ICU stays
• Cerebral function
• Post-operative hospital stays
Fast, easy set up
The shunt sensor is placed
in the cable head.
The cable head, with sensor
attached, is placed in the calibrator.
The sensor and probe head are
installed in the circuit with two
luer connections. The design
allows placement in a variety of
circuit locations.

Centers trust only the CDI System 500.
