Recirculation, Oxygenator Blood Volume and Cardiac Output Measurements During Extracorporeal Membrane Oxygenation
May 25, 2016 updated by: Transonic Systems Inc.
Measurement of Recirculation, Oxygenator Blood Volume and Cardiac Output in ECMO Using a Modified Transonic Systems (tm) HD02 Monitoring System
This study is to test the usefulness of ultrasound dilution measurements in patients on extracorporeal membrane oxygenation.
Measurements may include; efficiency of support (recirculation), amount of clotting in the oxygenator (oxygenator blood volume), and how well the heart is working (cardiac output).
At the present time there are no devices available to perform these functions.

Detailed Description
At the present time there are no devices available to measure recirculation, oxygenator blood volume and cardiac output in patients on extracorporeal membrane oxygenation.
The study uses an external monitor, laptop computer, clamp on flowsensors and ultrasound dilution technology to measure blood flow.
Measurements are made by injecting 0.5 - 1 ml/kg of sterile isotonic saline into the patient's extracorporeal circuit.
The subject will be monitored throughout the measurements.
The measurements will be coordinated with the regular care of the extracorporeal circuit.
