Arterial Doppler
An Arterial Doppler is a non- invasive exam using Doppler to evaluate the arterial blood flow and to detect blockages in the upper or lower extremities.
Q: What can I expect during an arterial Doppler?
A: You will be asked to remove clothing from the waist up or waist down depending on whether you have scheduled an upper or lower extremity arterial Doppler. You will be given a gown and sheet to wear during the examination. The technologist will perform the procedure lying on your back. The technologist will take blood pressures in the arms, legs and toes. When evaluating the blood flow you will hear a noise comparable to your heartbeat. Your doctor may request that the test be done with exercise as well. The exercise portion of this study involves walking on a treadmill at a normal rate for 5 minutes. Following the blood pressures the data will be reviewed and you may or may not proceed with an Ultrasound evaluation. The examination will take approximately 1 to 1 1/2 hours.
Q: What are the risks involved in an arterial Doppler?
A: Since the examination is non-invasive, there are no dyes or x-rays used, there is no pain or risk involved.
Q: Is there preparation involved?
A: You may eat, drink and take daily medications as usual.
