What is ABPI and how is It measured?
It is a ratio composed of the blood pressure in the brachial artery and the pressures in the foot arteries (dorsalis pedis and the posterior tibial artery). This guide provides a step by step approach to performing ABPI measurement in an OSCE setting.
What is ABPI in OSCE?
ABPI is a ratio composed of the blood pressure of the upper arm (brachial artery) and the blood pressure of the lower limb (dorsalis pedis and the posterior tibial artery). This guide provides a step-by-step approach to performing ABPI measurement in an OSCE setting.
What is the tbpi and ABPI?
Calcified vessels in diabetes sufferers will lead to artificially high ABPI values due to vessels which are not compressible. In such cases measure the Toe pressure (with a special toe cuff) rather than the ankle pressure. This is called the Toe Brachial Pressure Index (TBPI).
What is the difference between left and right ABPI?
Left ABPI = (highest pressure of either left PTA or DP) ÷ (highest brachial pressure) Right ABPI = (highest pressure of either right PTA or DP) ÷ (highest brachial pressure) Erroneous results can occur due to:
What is the ABPI?
Can diabetes cause high ABPI?
What does an ABPI show?
The ankle brachial pressure index (ABPI) provides an index of vessel competency by measuring the ratio of systolic blood pressure at the ankle to that in the arm, with a value of 1 being normal.
How is ABPI done?
Divide the highest ankle systolic pressure in each of the posterior tibial and dorsalis pedis arteries* in both feet by the highest brachial systolic pressure from each arm; the lowest resulting value is the patient's overall ABPI.
What is a good ABPI?
In a normal individual, the ABPI is between 0.92 and 1.3 with the majority of people having a ratio between 1 and 1.2. An ABPI above 1.3 is usually indicative of non-compressible blood vessels. An ABPI <0.9 indicates some arterial disease. An ABPI >0.5 and <0.9 may be associated with intermittent claudication.
Why would you do an ABPI?
The ankle brachial pressure index (ABPI) test is widely used to diagnose PAD, as well as assess how well you're responding to treatment. If your circulation is healthy, the blood pressure in both parts of your body should be exactly or almost the same. This would make the result of your ABPI 1.
What are three signs symptoms that can accompany peripheral vascular artery disease?
Numbness, weakness, or heaviness in muscles. Pain (described as burning or aching) at rest, commonly in the toes and at night while lying flat. Paleness when the legs are elevated. Reddish-blue discoloration of the extremities.
What does a blocked artery in leg feel like?
Claudication is a symptom of a narrowing or blockage of an artery. Typical symptoms of claudication include: Pain, a burning feeling, or a tired feeling in the legs and buttocks when you walk. Shiny, hairless, blotchy foot skin that may get sores.
What ABPI is safe for compression?
ABPI 0.8–1.3 — compression stockings are safe to wear. ABPI greater than 1.3 — compression should be avoided, as high ABPI values may be due to calcified and incompressible arteries.
What does a low ABPI mean?
Having a low ABPI ratio is an independent risk factor for cardiovascular disease including fatal and nonfatal complications. 46,47. In addition, the lower the ABPI value, the higher the risk of all-cause and cardiac mortality in patients with peripheral vascular disease. 48.
When should an ABPI be performed?
The role of ABPI assessment in wound management All patients with a lower limb wound – but particularly a leg ulcer – should undergo ABPI testing, as should patients who are considered to be at high risk (e.g. due to diabetes or immobility) or presenting with lower limb-related changes (Wounds UK, 2015).
What is the treatment for blocked arteries in the legs?
A graft is used to redirect blood flow around a blocked or narrowed artery. A graft can be a blood vessel from another part of the body or a synthetic substitute. In some cases, angioplasty or surgery may be necessary to treat peripheral artery disease that's causing claudication: Angioplasty and stent placement.
What happens at ABPI test?
A small amount of gel will be placed on your arm and your ankles, and a “pencil” like device called a handheld doppler will be used to listen to the blood flow. The blood pressure cuffs will be pumped up to determine the blood pressure at your arms and ankles. This may feel tight but should not be painful.
How is vascular disease diagnosed?
If you doctor suspects vascular disease, he or she may order non-invasive vascular testing. These are simple and painless tests using ultrasound to determine the presence, location, and severity of vascular disease.
How long does an ABPI test take?
The investigation takes up to one hour. During the test, you may hear some “swooshing” noises from the handheld doppler. These sounds are normal.
Is an ABI test painful?
The blood pressure cuffs might cause pain on the arm and leg while they inflate. But this discomfort is temporary and should stop when the air is released from the cuff. Severe leg pain might require a different imaging test of the arteries in the legs.
What is the procedure for a arterial Doppler?
During the exam: A water-soluble gel is placed on a handheld device called a transducer. This device directs high-frequency sound waves to the artery or veins being tested. Blood pressure cuffs may be put around different parts of the body, including the thigh, calf, ankle, and different points along the arm.
How do you perform a Doppler assessment?
Hold 8MHz Doppler probe gently over the brachial pulse until a good signal is obtained The best Doppler signal will be obtained with the probe at an angle between 45 – 60° to the artery. The artery may not be parallel to the skin and adjustment of the probe may be required to obtain a good signal.

What is the ABPI?
The ankle-brachial pressure index (ABPI) is a non-invasive method of assessing peripheral arterial perfusion in the lower limbs. ABPI is a ratio composed of the blood pressure of the upper arm (brachial artery) and the blood pressure of the lower limb (dorsalis pedis and the posterior tibial artery). This guide provides a step-by-step approach to performing ABPI measurement in an OSCE setting.
Can diabetes cause high ABPI?
Ask if the patient has diabetes: individuals with diabetes often have calcified vessels which are less compressible. These calcified vessels can, therefore, cause misleadingly high ABPI results. In such cases, the toe pressure can be measured instead of the ankle pressure (using a special toe cuff). This is known as the toe brachial pressure index ...
