PADnet Testing Part 3

A PADnet Arterial Test can provide early detection of P.A.D. when treatment options are broadest (incorporating both lifestyle modification, and non-invasive and invasive therapeutic options). The PADnet detects blockage in arteries and the quality of blood flow using pulse-volume recordings and segmental blood pressure measurements. Given appropriate signs and symptoms, a PADnet + Post-Exercise test may be necessary.
Before Your Test
Getting ready for your test requires little effort. You will be asked to remove clothing that covers your arms and legs, keeping your underwear on. You may be asked to remove your shoes and socks as well. A gown may be provided, or you may bring shorts to wear. This test often takes 15-20 minutes. Be sure to allow extra time to check-in.
  • Do not smoke or use tobacco 30 minutes prior to your PADnet+ exam. Smoking constricts the peripheral arteries and can interfere with the results.
  • If you think you cannot tolerate lying flat on the exam table, please let us know. 
During Your Test
You will lie down on the exam table. Pressure cuffs will be wrapped snugly around your arms, above your knees, calves, and ankles. The technician will inflate the cuffs, and the sensors in the machine will record the pulse waves that correspond to each beat of your heart.
Blood pressure will be recorded at your arms and ankles also. The ABI (Ankle-Brachial Index) is measured by the ratio between these pressures. P.A.D. is diagnosed if your ankle pressure is 99% or lower than your arm pressure. With severe narrowing, the ABI may be less than 50%.
You may be asked to perform toe-ups or to walk on a treadmill until symptoms are induced. After exercise, you will lie down on the exam table and repeat the arm and ankle tests.
If the ABI and/or waveforms are abnormal, your doctor may recommend additional diagnostic tests.
After Your Test
You may return to your normal routine right after the test. Your doctor will let you know when the results are ready.
