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.

Three adhesive sensor patches (similar to ECG patches) will be placed on the chest and a sensor similar to a pulse oximeter will be placed on the toe. The sensors will be connected to an electrical amplifier that produces a waveform.

Establishment of a Dataset to Create an Algorithm to Measure Cardiac Output
The primary outcome of this work is to establish a dataset that would enable the calculation of a predicted cardiac output using waveform analysis from multiple sensors. The primary outcome of this work is the number of subjects that successfully contributed data.
Time frame: 8 hours post cardiac surgery
