Development of a Minimally Invasive Cardiac Output Monitoring Device for Critically Ill Patients

The overall goal of this collaborative study is to advance the novel "pulse contour analysis" to the point at which it can be incorporated into a real-time device. The specific objective is to establish an auto-calibration algorithm that conveniently yields cardiac output (CO) in units of liters-per-minute. To achieve this objective, the waveforms for analysis and reference pulmonary artery catheter CO measurements will be recorded from critically ill patients and then analyzed off-line at Retia Medical. Successful completion of this study may ultimately help lead to improved outcomes of critically ill patients.
