What Bioengineers Should Know About Flow Measurement for Organ Preservation Devices

By John Haberstock24 Mar 2020


Thousands of patients are awaiting organ transplants, but due to the lack of organ availability, many of these patients die. 

Once a human organ is harvested for transplant, the race is on to get it into the recipient within hours. During this interim, the harvested organ is preserved by an organ perfusion system that continually perfuses the organ. Transonic’s capability to Screen Shot 2020-02-11 at 2.15.34 PMmeasure volume flow rate of blood or other physiological solutions makes its Tubing Flowsensors the ideal “flow inside” solution for organ perfusion systems1.

By measuring flow, perfusate flow can be optimized within the perfusion system designed to maintain transplanted organs until their implantation. 

Flow optimization reduces perfusion damage to the harvested organ, which ensures longer viability of the organ. Transonic’s Transit-time Ultrasound (TTU) flow measurement through sterile tubing is the gold standard for flow verification and is an ideal quality measure in organ preservation devices where consistent flow measurements can signal the difference between organ viability and failure.
