Doppler Overview

The Doppler monitor provides audible (primary) and visual (secondary) feedback of blood flow when connected to the implantable Cook-Swartz Doppler Probes and extension cables.

By allowing you to see and hear the presence or absence of blood flow, the Doppler system can alert you to flap failure in time to perform a salvage procedure.

Intended use
Monitoring blood flow in vessels intraoperatively and following reconstructive microvascular procedures, reimplantation, and free-flap transfers.

    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 have established the Doppler Blood Flow Monitoring System as a trusted complement to clinical monitoring that can contribute to more favorable outcomes:

    37%+ lower
    failure rates3

    57–73% higher
    salvage rates3

    Fewer returns
