The Terumo CDI-550 Blood Parameter Monitoring System is a highly trusted, legacy medical device designed to provide continuous, real-time monitoring of critical blood parameters during cardiopulmonary bypass procedures. By delivering precise measurements of pH, partial pressure of carbon dioxide (pCO2), partial pressure of oxygen (pO2), potassium (K+), and temperature, this system empowers perfusionists and surgical teams to make rapid, well-informed clinical decisions.

Utilizing advanced optical fluorescence technology, the CDI-550 offers exceptional accuracy without requiring frequent blood sampling. The system also calculates essential secondary parameters, including oxygen saturation, bicarbonate levels, base excess, and oxygen consumption, providing a comprehensive overview of the patient's physiological status throughout the procedure.

Designed with a user-friendly interface and a clear display, the CDI-550 integrates seamlessly into the clinical workflow of cardiac operating rooms. Its robust self-calibration features and system diagnostics ensure consistent performance and reliability when it matters most.
