What is a doppler ultrasound scan?

The Doppler test is a safety check and is similar to having your blood pressure taken but is measured from both your arms and ankles.

The test can be done using either a handheld machine or using a machine that uses dual cuffs to simultaneously take measurements. This machine is called a Microlife ABI.

What do I need to do to prepare for the test?

Please wear something with either loose or short sleeves. You must also be able to roll your trousers up to mid-calf. You may eat and drink normally before the test. For the test you will be asked to remove your socks/stockings and shoes.

What will happen?

An inflatable cuff will be applied to your upper arm and your ankle. You will feel the cuff becoming tight around your arms and ankles as the reading is measured. If you are concerned about this, please discuss it with your nurse/clinician.

Handheld Doppler

You will be asked to lay flat and rest for 20 minutes so your blood pressure settles. It may be a good idea to visit the toilet first to ensure you are comfortable.

You will then have a blood pressure cuff applied to your arm. Instead of using a stethoscope the Doppler sensor/probe is used to listen to your blood flow. To allow the sensor/probe to pick up a signal a small amount of gel is used on your skin.

When the pressure is being measured you will be able to hear the sound of your blood as it moves through the blood vessels on the Doppler.

This will be carried out on both arms and legs. You may only have a problem with one leg, but it is important that the blood flow in both legs is checked.

Microlife ABI

No rest period beforehand is required for this test. Cuffs are placed on both arms then inflated while a baseline blood pressure reading is taken.

One cuff stays on the arm while the other cuff is then placed on an ankle and the cuffs are inflated again. A reading is taken. This process is repeated on the other ankle.

The end reading from your test will allow your nurse/clinician to decide if you are suitable for compression bandaging/hosiery or if further investigations are appropriate.

The results of the test will be forwarded to your GP. Please contact the clinic if you have any queries on 0151 488 8467.
