Using Toe Pressures to Assess Arterial Foot Health

The effect of diabetes on the feet and lower limbs has been well established both in literature and in clinical studies. Changes in the body can ultimately impact both the larger and smaller arteries in the lower limbs. Calcification of arteries as well as formation of thrombi (Blood clots) may lead to further problems that can end in death. As such, ankle systolic blood pressure measurements have been an important process in evaluating and monitoring lower limb arteries for onset of diseases such as peripheral arterial disease and critical limb ischaemia. Currently the most widely accepted method of assessing this is the Ankle Brachial Pressure Index (ABPI). Though this method is effective in identifying blockages in blood flow, recent studies have shown it to be unreliable in elderly patients, those with diabetes or chronic renal failure because the peripheral arteries may be incompressible as a result of calcification or blockages in these smaller arteries.

What does the Systolic Toe Pressure Machine Detect?

The newest technologies look to assess the systolic blood pressure in the toes as well as toe pressure indices. The readings are usually taken at the hallux. The results of these studies can be used to identify or screen for a number of medical conditions including:

  • Blockages in large and small blood vessels
  • Arterial insufficiency
  • Cardiac dysfunction
  • Ischaemia/intermittent claudication
  • Necrosis and amputation risks.
