Terumo CDI OneView - How the System Works

System Overview
How the System Works
The CDI OneView System is an AC-powered, microprocessor-based system. The system
uses an optical uorescence technology to measure blood gases, pH and potassium.
It additionally uses an optical reectance technology to measure oxygen saturation,
hematocrit and hemoglobin.
Optical uorescence measurements are taken through a Blood Parameter Module
(BPM) connected to a disposable Shunt Sensor. Optical reectance measurements
are taken through the Hematocrit/Saturation (H/S) Probe connected to a disposable
cuvette. Shunt Sensors and cuvettes are incorporated in the extracorporeal circuit.
Flow measurements are taken through a Flow Sensor attached to tubing on the
extracorporeal circuit.

Any user of the CDI OneView System must read and understand all the information
in this manual — the CDI OneView System Operator’s Manual — as well as the
instructions for use included with all associated disposables before using the system.
Special attention must be paid to the following crucial safety information:
Warning
 The Shunt Sensor accessory contains Germall II in the calibration
uid. A potential byproduct of Germall II may be formaldehyde.
Exposure may cause adverse reactions in patients with
formaldehyde sensitivity.
 The Shunt Sensor is heparin treated and should not be used with
heparin sensitive patients. Devices with heparin treated surfaces
may cause an adverse reaction.
 Use of the following substances can potentially cause inaccuracies
in displayed values: Indocyanine green (Cardio-Green), Methylene
Blue, or other intravascular dyes, carboxyhemoglobin or
situations such as dyshemoglobins, hemoglobinopathies,
elevated bilirubinemia and/or icterus (jaundice).
 Verify the accuracy of displayed values with another source (i.e.,
laboratory, point-of-care blood gas analyzer or independent ow
measurement) before initiating treatment.
 Possible explosion hazard. Do not use the CDI OneView System in
the presence of ammable anesthetics or other explosive gases.
 Do not use an apparently malfunctioning device in a procedure.
