CDI® 550

Blood Parameter Monitoring System

Description

Real-time monitoring of DO2 as one of 12 key blood parameters

The proven technology of the CDI® Blood Parameter Monitoring System 550 delivers continuous blood parameter readings, providing early detection of changes in patient status during cardiopulmonary bypass surgery.


CDI® System 550

Based on optical fluorescence and reflectance technologies, the CDI® System 550 continuously measures or calculates 12 critical blood parameter values during cardiopulmonary bypass. Access to continuous information is a key advantage in optimum patient management because it enables clinicians to react without delay to changes in blood parameter values.


Easy Set Up and Calibration

There is no warm-up time required for installation or calibration. Installing the sensor in the shunt line requires a few, simple luer connections. The shunt sensor also can be added after the initiation of bypass, facilitating set up in emergency cases.


System Features
  • Self-diagnostic system verifies proper functioning of electronics and optics.
  • System alerts provide visual and audible indicators when parameters fall outside user-specified limits.
