​​Systolic pressures are measured in sequence at different points along the legs, and compared to the pressure in the arms.  By comparing the pressures, the physician can detect suspected blockages. 

Before The Procedure
There are no special preparations for this test.  You will be taken to the Vascular lab in a wheelchair or by stretcher.  If a family member would like to go with you, they must be prepared to walk a great distance quickly. 

During The Procedure
If you go by wheelchair, you will be asked to lie on a bed in an exam room for the test.  There will be a short wait while the technician reviews your chart.  Pressures will be taken on your arms.  Pressures will also be taken up and down your legs.  The technician will chart out these pressures on a map of the vascular system, and put it in your chart for your physician to review.

After The Procedure
After a brief wait,​ you will be taken back to your room by wheelchair or stretcher.  Your physician will explain the results of the test after he reviews the charted pressures.
