Segmental Pressure

A segmental pressure exam evaluates the blood flow in an extremity. It can reveal possible blocked or reduced blood flow that may be the source of various symptoms.

Before Your Procedure

  • You may eat normally. No preparation is required.

During Your Procedure

  • You will be positioned on an exam table.
  • This test is often performed on both arms or both legs, even if the suspected blood flow problem is only in one extremity. Both extremities are done for comparison.
  • Blood pressure cuffs are placed on one or both arms and/or legs. The blood pressure cuffs are placed in several different locations, depending on which vessels are being tested.
  • The blood pressure cuffs will inflate and deflate at various times during the exam.
  • A registered sonographer will place a doppler probe over the blood vessels and you may hear sounds that represent blood flow through those vessels.
  • The ultrasound machine then takes measurements of the blood flow.
  • Blood pressure cuffs are placed on one or both arms or legs and more measurements are recorded.
  • The blood pressure cuffs are placed in several different locations depending on which vessels are being tested.
  • The exam length is approximately 60 minutes.

After Your Procedure

  • You may return to normal activity.
  • A radiologist will interpret the results and send a report to your doctor.
  • Your physician will contact you to discuss the results in approximately 3-4 days after the exam.

Dear Friends and Neighbors,

CentraCare care givers have been working around the clock for more than 20 months to care for you, your families and friends during COVID. We are committed to caring for every Minnesotan who needs us, and nothing will prevent us from doing so – even during these never-seen-before times.

The challenge of providing this level of care is that our hospital beds are often full. ERs in all of our hospitals are packed. And our clinical teams are exhausted. Early in the pandemic, our community stepped up in amazing ways to help us. We ask that you again join us in fighting this pandemic together.

How can you help?

  • Please get your COVID vaccines and booster shots. They are proven safe and effective in reducing COVID illness, keeping people out of the hospital, and preventing death.
  • If your situation is not an emergency, please use other care options, including:
  • If this is a medical emergency, call 9-1-1, or visit the ER.

Together, we can do this. Thank you for your support.

Ken Holmen, MD
