The description details a microprocessor-based system utilizing electro-optics, fluorescence chemistry, and optical reflectance to measure and calculate blood parameters in real time. There is no mention of AI, ML, or related concepts in the intended use, device description, or performance studies.
No.
The device is for monitoring blood parameters and does not directly provide therapy.
Yes
Explanation: The device monitors various blood parameters such as partial pressure of oxygen and carbon dioxide, pH, potassium, oxygen saturation, hemoglobin, and temperature. This real-time measurement and display of physiological data are used to assess the patient's condition, which aligns with the definition of a diagnostic device.
No
The device description explicitly lists multiple hardware components, including a monitor, parameter modules, probes, calibrator, and sensors, which are integral to its function of measuring blood parameters.
Based on the provided information, the CDI System 550 is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the device provides "continuous, on-line monitoring of the extracorporeal partial pressure of oxygen and carbon dioxide, pH, potassium, oxygen saturation, hemoglobin and temperature." This indicates that the device is monitoring blood parameters within the extracorporeal circuit, which is outside the body but still part of a patient's circulating blood.
- Device Description: The description details how the device interacts with the extracorporeal circuit using sensors and cuvettes inserted into the blood flow. It measures parameters in "real time" from the blood as it passes through the system.
- Lack of In Vitro Testing: The description of performance studies does not mention any studies involving testing of samples outside the body in a laboratory setting, which is characteristic of IVD devices. The studies focus on electrical safety, software validation, and design verification.
IVD devices are typically used to examine specimens (like blood, urine, or tissue) that have been removed from the body to provide information about a person's health. The CDI System 550 is monitoring blood in situ within a medical circuit connected to the patient.

Intended Use / Indications for Use
The CDI System 550 provides continuous, on-line monitoring of the extracorporeal partial pressure of oxygen and carbon dioxide, pH, potassium, oxygen saturation, hematocrit, hemoglobin and temperature. In addition, calculated values of base excess, bicarbonate, oxygen saturation, oxygen delivery and oxygen consumption may also be provided. These parameters are displayed at either actual temperature or adjusted to 37°C. For documentation purposes, the systems integral printer provides a hard copy of displayed parameters.

Device Description
The CDI System 550 is an AC-powered (battery back-up) microprocessor-based device used with the following components/accessories:
- CDI 550 Monitor
- Arterial and/or Venous Blood Parameter Modules (BPM)
- CDI Hematocrit/Saturation (H/S) Probe
- CDI 540 Gas Calibrator and Calibration Gases (A and B)
- CDI 510H Shunt Sensor
- Shunt Bypass Line
- CDI H/S Cuvette with or without extension tubing
- Monitor Mounting Hardware (Pole Clamp and Cable Head Bracket)
- Printer Paper
The CDI System 550 measures blood parameters in real time by utilizing a microprocessor based monitor, electro-optics modules (i.e., BPM and H/S probe), fluorescence chemistry technology, and optical reflectance technology. The electro-optics modules connect the monitor to the disposables (i.e., shunt sensor or cuvette) which are inserted into the extracorporeal circuit. Light is emitted from the modules, and the optical responses from the blood via the sensor(s) are measured by the monitor. The blood parameters are measured or calculated by the CDI 550 Monitor in real time, and displayed to the user via a graphical LED display.

Comparison of Technological Characteristics to Predicate Device
The CDI System 550 uses a microprocessor based monitor, electro-optics modules, fluorescence chemistry technology, and optical reflectance technology for measuring blood parameters in real time. The technology between the subject and predicate devices is equivalent and provides the basis for the following system functions:
- Blood parameters are measured or calculated by the monitor in real time and . displayed to users via a graphical LED display.
- . Monitors and displays the following blood parameters:
Measured using the BPM
- Partial pressure of oxygen (PO2) O
- Partial pressure of carbon dioxide (PCO2) o
- pH O
- Potassium (K+) O
- O Temperature
Calculated from the above BPM measured values
- Bicarbonate (HCO3) O
- Base Excess (BE) O
- Oxygen saturation (SO2) (if the measured value is not available from the H/S O Probe)
Measured using the H/S Probe
- Oxygen saturation (SO2) O
- Hematocrit (Hct) o
- Hemoglobin (Hgb) O
- . Blood flow rate. O. is either entered manually or via a serial interface between the CDI Monitor and the heart-lung machine. Blood flow rate can be displayed and is used to calculate oxygen consumption (VO2).
The following differences exist between the subject and predicate devices:
- A new calculated blood monitoring parameter, Oxygen Delivery (DO2), was ● added allowing users to monitor patient DO2 levels during cardiopulmonary bypass. The Indications for Use statement was also updated to reflect this new parameter.
- . Modifications to the alarms scheme pursuant to IEC 60601-1-8 (Edition 2.1): Medical electrical equipment - Part 1-8: General requirements for basic safety and essential performance - Collateral Standard: General requirements, tests and guidance for alarm systems in medical electrical equipment and medical electrical systems.
- . Expanded hematocrit (HCT) and hemoglobin (Hgb) operating ranges and their corresponding modified accuracy claims.

- Improved temperature correction algorithm which resulted in modified blood parameter module (BPM) accuracy claims.
- . Improved performance prior to in vivo calibration as measured by the HSAT Module.
Performance Data
Biocompatibility Testing
The CDI System 550 Monitor and 540 Calibrator do not come into contact with the patient, and there have been no changes to the disposable accessories. Biocompatibility testing was not required to demonstrate the substantial equivalence of the CDI System 550 to the predicate device and is not included as part of this premarket notification.
Electrical Safety and Electromagnetic Compatibility (EMC)
Evaluation for electrical safety and EMC testing was conducted on the CDI System 550. The CDI System 550 complies with the IEC 60601-1 standard for electrical safety and the IEC 60601-1-2 standard for EMC.
Software Verification and Validation Testing
Software verification and validation testing was completed successfully. The fullfillment documentation is provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for CDI System 550 is considered a "moderate" level of concern since a malfunction or latent design flaw of the software device could lead to an erroneous diagnosis or a delay in delivery of appropriate medical care that would likely lead to minor injury.
Design Verification and Validation Testing
Design verification testing was conducted and demonstrates that the CDI System 550 performs pursuant to the defined design input requirements for the subject device. Design validation, including simulated use testing, was conducted and demonstrates that the CDI System 550 meets the defined design input requirements for the subject device.
Animal Study
Animal testing was not required to demonstrate the substantial equivalence of the CDI System 550 to the predicate device and is not included as part of this premarket notification.
Clinical Studies
Clinical testing was not required to demonstrate the substantial equivalence of the CDI System 550 to the predicate device and is not included as part of this premarket notification.

Conclusion
The technological characteristics and fundamental scientific technology of the subject device have not changed from the predicate device. Software, design verification, and design validation testing have confirmed that the modifications do not adversely impact system performance. The CDI System 550 is substantially equivalent to the currently marketed CDI System 500 cleared under K133658.
