Doppler – Blood Flow Monitor

Doppler Blood Flow Monitoring System



The Cook Doppler Monitoring System is designed to help detect early free flap failure.

Doppler offers the surgeon both visual and audible tracking of blood flow continuously, even during a procedure. When compared to clinical monitoring alone, it’s associated with significantly higher salvage rates.

This highly mobile device can be used in theatres and be moved with the patient into recovery and the ward, enabling constant monitoring of blood flow.

Clinical Evidence

The literature shows that the use of the Cook Doppler can:

  • Decrease returns to surgery – Because the Doppler system offers objective monitoring at an earlier stage, it has been associated with a decrease in returns to surgery (1).
  • Offer higher salvage rates – When compared with clinical monitoring alone, Doppler offers higher salvage rates (2,3) a systematic review and meta-analysis showed an increase of between 57% and 73% with the Doppler (2).
  • Offer lower failure rates – It has also been shown that using an implantable Doppler may reduce the number of flap failures by at least 37% (2).
