Extracorporeal Membrane Oxygenation (ECMO) Circuits
“Use of the Transonic Flowmeter allows the ECMO specialist to monitor actual patient blood flow and hemofilter shunt enhancing patient care management” Berube, MC et al, 12th Annual CNMC Symposium on ECMO & Advanced Therapies for Respiratory Failure, 1996 Keystone, CO.
Extracorporeal membrane oxygenation (ECMO) is the use of prolonged extracorporeal cardiopulmonary bypass (CPB) in patients with acute, reversible cardiac or respiratory failure.
By providing an independent measure of delivered blood flow, a Transonic Tubing Flowboard and its companion Clamp-on Flowsensor serve as an invaluable safety and quality device for the ECMO circuit. They provide noninvasive, sterile measurements without any contact with the fluid or interruption of tubing. The measurement is stable at low flows used in ECMO treatment. It has a stable and low zero offset and its calibration can be adjusted on site.
Transonic flow measurements are the standard used by the biomedical industry with which they calibrate and validate other pumps. Now, as sophisticated devices are used to monitor ECMO delivery and treatment, Transonic Flowboards and Flowsensors imbedded in monitoring systems are essential for the verification of flows through ECMO circuits.
