Features and benefits.

The success of a free flap—and the ability to salvage a flap, if necessary—depends on the sensitivity and accuracy of your monitoring. The Doppler Blood Flow Monitoring System is an evidence-backed technology that boosts your monitoring capability in three ways:

More placement options

Monitor arteries and/or veins, end to end or end to side, proximal or distal to the anastomosis.

Access to buried flaps

Monitor buried flaps—including flaps in challenging anatomical locations that are difficult to evaluate clinically—and potentially detect flap compromise earlier.¹ In specialties such as head and neck surgery, where buried flaps are common, the salvage rates with the Doppler system can be more than double that of conventional monitoring.²

Proven performance

Over twenty years of clinical evidence has established the Doppler Blood Flow Monitoring System as a trusted complement to clinical monitoring that can contribute to more favourable outcomes compared to conventional monitoring:
