A Doppler assessment is used to detect any arterial or vascular insufficiencies in the body's circulation. A Doppler machine (similar to that used in detecting a baby’s heartbeat on pregnant women) is a hand held device which is used to amplify a received signal into an audible sound. By taking blood pressure readings in both arms & legs, and using the doppler that help us to 'listen' to the veins & arteries, we can then apply a mathematical formula to the readings that help us to determine how healthy the circulation is. There are numerous reasons why we should wish to carry out this task, and the results will very much determine what treatment is then offered. To get the most accurate result we would ask that patients arrive at the surgery in good time - so they are well rested, and their blood pressure is as stable as possible. This task is not to be rushed and that is why we allow approximately 40 minutes for this procedure.
The nurses will need access to your upper arms and lower legs so it would be helpful to wear loose fitting clothing that can be pulled up or down. Tights, stockings and socks will need to be removed but any dressings can remain in place.
