The CDI OneView System is Terumo’s next perfusion innovation.

The CDI OneView System provides the precision, control, and confidence perfusionists demand for optimal patient management. With visibility to a breadth of critical Goal Directed Perfusion (GDP) values, such as Oxygen Delivery (DO2), Oxygen Extraction Ratio (O2ER), Area Under the DO2 Curve (AUC), Measured Flow (Q), Cerebral Oximetry (rSO2) and blood gases in the same view, perfusionists can clearly see the parameters that matter most.

CDI OneView System Benefits

Critical information, clearly in view.

The CDI OneView System provides perfusionists with continuous insight to 22 critical parameters enabling the cardiovascular team to deliver goal directed therapy designed to reduce AKI. The system measures patient parameters including Potential of Hydrogen (pH), Partial Pressure of Carbon Dioxide (pCO2), Partial Pressure of Oxygen (pO2), Potassium (K+), Temperature, Oxygen Saturation (SO2), Hematocrit (HCT), and Hemoglobin (Hgb). It calculates Base Excess (BE), Bicarbonate (HCO3-), Cardiac Index (CI), O2ER, Oxygen Consumption (VO2), DO2, and AUC. The CDI OneView System is designed for connectivity to cerebral oximetry devices so all critical information is in view. New Flow Sensors allow for directly measured blood flow values. The CDI OneView System delivers important information for GDP strategies.

Designed for improved real-time insight.

The CDI OneView System boasts a smaller, intuitive interface for optimal visibility of critical patient values. Perfusionists can customize case profiles to view the information according to personal or institutional preference. Teams can analyze and see data in real-time, in both numeric and graphical formats, allowing them to identify patterns, spot trends and gain insight. Case profiles provide alerts and alarms to ensure attention to parameters that may need immediate adjustments to stay within goal directed clinical ranges.

Advanced, flexible and modular beyond compare.

Aimed at maximum configurability the CDI OneView System is designed for flexible customization. The new probe designs can be configured for arterial or venous gases, and arterial or venous saturation for red blood cell measurements. Flow sensing technology, rSO2 connectivity, communication from external heart-lung machines (HLM) for flow data, along with data management connectivity enable customization to suit varying medical practice. The CDI OneView System is a complete perfusion solution.

The Value of Accurate DO2 Measurements in Relation to AKI

Research confirming the significant and serious impact of AKI to patient outcomes is extensive. Clinicians and hospital systems widely acknowledge the importance of minimizing AKI due to the substantial morbidity, mortality, and financial implications.

Minimize the Risk of AKI

Research indicates that the use of a GDP strategy aimed at avoiding a DO2 < 280mL/min/m2 on cardiopulmonary bypass (CPB) is effective in reducing the risk of AKIN stage 1 AKI after cardiac surgery.1

Reduce Mechanical Ventilation Time and Length of ICU stay

The management of indexed oxygen delivery (DO2i) in relation to indexed O2ER following CPB has been found to be more specific in terms of negative predictive value for hyperlactatemia compared to the use of cardiac index in relation to mixed venous oxygen saturation. That management can correlate with postoperative better outcome especially in terms of serum creatinine, mechanical ventilation time, and intensive care unit stay.2

Avoid Significant Hospital Costs Attributed to AKI

According to a 2018 study, the mean total index hospitalization cost for cardiac surgery patients with AKI was $77,178 vs. $38,820 for those without AKI (p < 0.001). At the national level, the overall incremental annual index hospitalization cost associated with AKI was $1.01 billion.3

CDI OneView System Features

1. Processing Core

The Core serves as a connectivity hub, routing information from the Blood Parameter Module (BPM), Hematocrit/Oxygen Saturation (H/S) Probe, Flow Sensors and Interface Modules to the Touchscreen Display. May be conveniently mounted vertically or horizontally to the HLM or can be used on a flat surface.

2. Touchscreen Display

Graphical user interface and touchscreen technology provide quick access to clinician-defined customizable parameters and view configurations. Its compact, low-profile display lends to maximizing the view of the operative field.

3. Blood Parameter Module

The BPM can be employed in arterial or venous applications. Light emitting diode (LED) indicator lights display the assignment in red or blue. The housing has been designed for usability allowing smooth insertion to the Calibrator slot.

4. H/S Probe

The H/S Probe can be employed in arterial or venous applications. LED indicator lights display the assignment in red or blue. The spring clip was designed with user-friendliness in mind and can be detached for cleaning purposes.

5. Flow Sensors

Optional CDI OneView System Flow Sensors provide measured flow from the extracorporeal circuit. Directly measured flow is more accurate than calculated arterial flow from a roller pump. Blood flow rate is used to calculate critical GDP parameters. In pediatric cases with multiple circuit shunts, measured flow is highly desirable.

6. Flow Module

The Flow Module interfaces the Flow Sensor and the Core. All available sizes of CDI OneView System Flow Sensors can be used with the Flow Module. For multiple flow readings during a single surgical case, additional Flow Modules are required.

7. Calibrator

Rapid two-point gas calibration ensures the Shunt Sensor is operating according to designated specifications. The new small footprint and built-in handle provide transportability.

8. Data Modules
  • The HLM Data Module accepts flow input from the pumping system to use for calculations and allows the blood flow value to display on the CDI OneView System.
  • The rSO2 Module allows values from the Medtronic INVOS, Edwards ForeSight Elite®, and Nonin SenSmart® to stream and display on the CDI OneView System.
  • The Data Management System (DMS) Module allows the CDI OneView System data to stream to external data management systems or electronic medical records (EMR).
9. Shunt Sensor
  • Proprietary optical fluorescence technology is used to measure arterial and/or venous pH, arterial and/or venous pCO2, arterial and/or venous pO2, K+, and blood temperature.
  • Simple installation into the shunt line using luer connections.
  • May be added after the initiation of bypass, facilitating quick set up in emergency cases.
10. H/S Cuvette
  • Optical reflectance technology provides accurate readings of arterial and/or venous SO2, HCT, and Hgb.
  • The H/S Cuvette easily clips to the H/S Probe.
  • H/S Cuvettes are available in three sizes: ¼" x ¼", ⅜" x ⅜", and ½" x ½".
