This study will focus on determining;
- How accurate the test is in detecting poor circulation
- How it's accuracy compares to other commonly used tests, and
- Whether test results are linked to the chance of ulcer healing or amputation. Across 2 hospitals, 305 diabetic patients will be scanned using the focused ultrasound test as well as other commonly used tests to detect poor circulation. Their results will be compared to a full version of the ultrasound test to identify the most accurate.
In the UK, over 7,000 amputations are performed each year because of diabetes. Most of these (80%) occur when a foot wound, also known as an ulcer, does not heal. The most important cause of this is poor circulation to the feet. Currently, there are no accurate tests that foot specialists can use to detect poor circulation when they see patients. Because of this, poor circulation can be missed and its treatment delayed.
A focused ultrasound test at the ankle, using a sensor and gel on the skin, can detect poor circulation. It is safe, painless and I have previously proven that it can be learned and performed quickly. It may help avoid amputations by detecting poor circulation so that it can be treated quickly.

To our knowledge, the measurement of the transcutaneous oxygen pressure during walking is the only continuous method that estimates the importance of ischemia, bilaterally and segment of l...
The purpose of this study is to demonstrate the utility of the FlowMet™ device in the assessment of perfusion in subjects suspected of or being treated for critical limb ischemia, in com...
Diabetic foot patients with chronic limb ischemia and without the option for surgical or interventional revascularization were recruited and randomized to the transplant groups or the cont...
Comparative study of pressure (ankle-brachial pressure index) and flow (strain gauge plethysmography and reactive hyperaemia) measurements in diagnosis of peripheral arterial disease in patients with severe aortic stenosis.
The measurement of the ankle-brachial pressure index is a straightforward method for the detection of peripheral disease in the lower limbs. Only a few old studies with small numbers of patients have ...
Increased interarm systolic blood pressure difference (IASBPD) is associated with cardiovascular prognosis in the general population. This study aimed to evaluate whether IASBPD or ankle brachial inde...
Based on our previous reports, ipsilateral systolic toe pressure (STP) and toe-brachial index (TBI) have a strong association with midterm cardiovascular and overall mortality as well as with amputati...
In this essay, we question the sole use of mg/L (ppm) and the term DO (dissolved oxygen) when referring to oxygen supply in water, and discuss reasons for also reporting the partial pressure of oxygen...
Arterial stiffness is associated with longitudinal increases in blood pressure and hypertension development. A screened cohort was used to test whether increases in the ankle-brachial index (ABI) with...
Comparison of the BLOOD PRESSURE between the BRACHIAL ARTERY and the POSTERIOR TIBIAL ARTERY. It is a predictor of PERIPHERAL ARTERIAL DISEASE.
The blood pressure in the ARTERIES. It is commonly measured with a SPHYGMOMANOMETER on the upper arm which represents the arterial pressure in the BRACHIAL ARTERY.
The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).
The noninvasive measurement or determination of the partial pressure (tension) of oxygen and/or carbon dioxide locally in the capillaries of a tissue by the application to the skin of a special set of electrodes. These electrodes contain photoelectric sensors capable of picking up the specific wavelengths of radiation emitted by oxygenated versus reduced hemoglobin.
The blood pressure in the VEINS. It is usually measured to assess the filling PRESSURE to the HEART VENTRICLE.
