NCT01675063

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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.

    8 hours post cardiac surgery

Study Arms (1)

Retia Non-Invasive Sensors

OTHER

Sensors will be placed on the patient and connected to an amplifier that produces a waveform for 8 hours post cardiac surgery.

Device: Retia Non-Invasive Sensors

Interventions

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.
