Skin Perfusion Pressure Testing Q & A

What is a skin perfusion pressure test?

Skin perfusion pressure tests, or SPP tests, will assess if the tiny blood vessels in the foot and leg, known as capillaries, are obstructed or damaged in order to determine if the wound is getting enough blood to heal. Obstructed or damaged blood vessels can stop the wound from healing. Oxygen is required in order for wounds to heal. Blood vessels and the tiny capillaries carry oxygen to the skin of the foot and to the wounds. When these vessels are obstructed or damaged it can decrease the amount of blood, and therefore oxygen, to the wounds. Wounds that do not receive enough blood will not heal. The assessment of blood flow in the lower extremities is extremely important when managing foot ulcers or gangrene associated with peripheral artery disease, or PAD, as well.

How is the SPP test performed?

When the patients come in for their test they will be required to lie flat. A small sensor will be placed near the wound. Then a blood pressure cuff will be placed over the sensor. The test will identify how much blood is flowing to the skin surrounding the affected skin. The SPP takes roughly 5 to 10 minutes to perform for each location. Patients may have to have more than one site assessed.

What do I need to do before the test?

  • Do not smoke for at least two hours prior to the assessment.
  • Do not drink caffeine after midnight the night prior to the test.
  • Stay as still as possible throughout the assessment.
  • Do not talk, eat, or drink throughout the assessment.

What happens after the tests?

The sensors and blood pressure cuffs will be taken off and set aside. A dressing will be applied to the wound area if required. This test does not cause side effects. The physician will review the results with each patient and suggest a course of treatment.
