Calculating the ABI
- An ABI is calculated for each leg. The ABI value is determined by taking the higher pressure of the 2 arteries at the ankle, divided by the brachial arterial systolic pressure. In calculating the ABI, the higher of the two brachial systolic pressure measurements is used. ...
- Calculated ABI values should be recorded to 2 decimal places.

Do you elevate legs with chronic arterial insufficiency?
You should elevate your feet but not above the heart level. Extreme elevation slows arterial blood flow to the feet.
What are the 4 stages of PAD?
The American College of Cardiology/American Heart Association Practice Guidelines defines the presentation of PAD by four categories: asymptomatic, claudication, critical limb ischemia, and acute limb ischemia (ALI).
How do you measure arterial perfusion in lower extremities?
Imaging modalities such as computed tomography (CT) angiography, magnetic resonance imaging (MRI) angiography, and duplex ultrasound can accurately measure blood flow in the lower extremities; however, these are only surrogate markers for tissue perfusion.
What exercise is best for peripheral artery disease?
You could try walking up hills or stairs, or add an incline to your treadmill routine. Keep in mind: Peripheral artery disease took years to develop in your legs, and it will take a few months to improve your walking. Dr. Mohler says, “It's important to be patient with yourself.”
How can you tell the difference between arterial and venous insufficiency?
Venous insufficiency refers to a breakdown in the flow of blood in our veins, while arterial insufficiency stems from poor circulation in the arteries. Left untreated, both conditions may lead to slow-healing wounds on the leg.
Is arterial insufficiency the same as atherosclerosis?
One of the most common causes of arterial insufficiency is atherosclerosis or "hardening of the arteries." Fatty material (called plaque) builds up on the walls of your arteries. This causes them to become narrow and stiff. As a result, it is hard for blood to flow through your arteries.
What is considered the first symptom of peripheral arterial disease?
The classic symptom of PAD is pain in the legs with physical activity, such as walking, that gets better after rest. However, up to 4 in 10 people with PAD have no leg pain. Symptoms of pain, aches, or cramps with walking (claudication) can happen in the buttock, hip, thigh, or calf.
What is the most distinguishing characteristics of a arterial ulcers?
Arterial ulcers are characterized by a punched-out look, usually round in shape, with well-defined, even wound margins. Arterial ulcers are often found between or on the tips of the toes, on the heels, on the outer ankle, or where there is pressure from walking or footwear.
How can you tell the difference between arterial and venous insufficiency?
Venous insufficiency refers to a breakdown in the flow of blood in our veins, while arterial insufficiency stems from poor circulation in the arteries. Left untreated, both conditions may lead to slow-healing wounds on the leg.
Does arterial insufficiency cause edema?
Any edema is localized or can be associated with an infection. Pain is a significant symptom associated with arterial insufficiency. The pain may be described as intermittent claudication, which is pain during fast/prolonged ambulation or cramping of the muscles of the lower extremity on climbing many steps.
What is arterial insufficiency ulcers?
Arterial insufficiency ulcers result from ischemia due to lack of arterial blood flow supplying the area of the wound. The most common cause of arterial insufficiency is arteriosclerosis obliterans (ASO), though trauma and thrombosis can also impair arterial blood flow.
What happens if your arteries are narrowed?
Symptoms depend on where your arteries become narrowed: If it affects your heart arteries, you may have chest pain (angina pectoris) or a heart attack. If it affects your brain arteries, you may have a transient ischemic attack (TIA) or stroke. If it affects the arteries that bring blood to your legs, you may have frequent leg cramping ...
What is the term for a condition that slows or stops the flow of blood through your arteries?
Definition. Arterial insufficiency is any condition that slows or stops the flow of blood through your arteries. Arteries are blood vessels that carry blood from the heart to other places in your body.
Why is my blood flow so hard?
One of the most common causes of arterial insufficiency is atherosclerosis or "hardening of the arteries.". Fatty material (called plaque) builds up on the walls of your arteries. This causes them to become narrow and stiff. As a result, it is hard for blood to flow through your arteries. Blood flow may be suddenly stopped due to a blood clot.
What causes a narrowing of the artery?
Atherosclerosis is one of the commonest causes. In atherosclerosis, fat and cholesterol gets accumulated and adheres to the inner lining of arterial wall. It forms a plaque. This leads to narrowing of the artery.
What is arterial insufficiency?
Arterial insufficiency can be described as insufficient flow of blood in the arteries. This inadequacy occurs when the lumen (wall) of the artery becomes narrow or gets blocked partially or completely. Several medical conditions and environmental factors can precipitate the problem. Atherosclerosis, smoking, increase blood coagulation, etc are few important ones.
Why do my legs feel numb?
In case there is lack of blood flow in limbs, it may cause cramps and tingling numbness in legs. In severe cases, it can develop in gangrene. When eyes are involved, the patient may have vision trouble. Treatment of arterial insufficiency reduces the morbidity and mortality rate.
What is the best treatment for arterial insufficiency?
Blood thinning agents are recommended for all types of arterial insufficiency. Natural measures also play an important role in treating arterial insufficiency.
What are some examples of life threatening events?
This may become a life threatening event in certain cases. Example is heart attack and stroke. It can also occur as a result of embolism. Embolus is a blood clot. Usually emboli develop from the heart. It may travel in the blood stream and block the artery. Example is pulmonary embolism.
What causes a heart attack?
The symptoms depend on the organ or the site involved. If there is an insufficient flow of blood in the coronary arteries, then it may cause heart attack.

How to check for low extremity pulses?
The physical exam of your doctor may reveal decreased or absent lower extremity pulses and this may be confirmed by getting an ankle-brachial index (ABI). To do this, your doctor will take your blood pressure above the ankle and on both arms and use a handheld doppler to listen to the signal.
Why do arteries stretch?
In the early stages, even with the build-up, the arteries are still able to continue their usual function because the arteries can stretch to preserve the flow in the artery but eventually, as the cholesterol plaque gets bigger , the arteries are not able to stretch further and the plaque slowly narrows the arterial flow compromising the blood that’s supposed to pass by it .
How many people have peripheral arterial disease?
Peripheral arterial disease affects more than 200 million adults in the world and by the age of 70, the incidences of peripheral arterial disease increase up to 20%. (1)

How to tell if you have PAD?
Other signs that are often seen by the doctor during the physical exam of a patient with PAD are pallor or paleness, atrophy or decrease in size of a muscle, loss of hair over the area with claudication, cool skin on palpation, the presence of bruit, pain on palpation and decreased pulses.
Why does ischemia occur in the lower extremity?
Because of this blockage, ischemia happens more commonly in the lower extremity. In other cases, the ischemia may be caused by an embolus. An embolus is something that travels in the bloodstream and causes a block in the vessel. It could be in the form of a blood clot that has detached from its original area, air, or any bodily substance.
