Peripheral artery disease is an inflammatory disease that most often affects the arteries of the lower extremities, less often the upper ones. During PAD, the blood vessels are narrowed and normal blood flow is disturbed, leading to insufficient blood supply. Accurate diagnosing is essential for proper treatment, and pulse volume recording is the method to detect the PAD disease and understand its severity. The procedure is required to evaluate perfusion (the passage of blood) in people with inadequately compressible arteries, and the arterial exam helps to obtain useful information about blood flow in the limbs.
How to prepare for the PVR medical test?
During the study, the specialists will apply a medical device, known as blood pressure cuffs. Another pivotal component for receiving the needed details and assess how blood moves through vessels is the Doppler device. The purpose of the medical PVR procedure is to get two measurements of the pressure in the arms and legs and compare them. If a patient is healthy and doesn’t suffer from PAD, these two numbers will be the same. If these numbers are different, it means that you have issues with your arteries, and the condition must be competently handled to treat it and eliminate fatty deposits that are developed in arteries. For a hassle-free evaluation of the blood pressure, it is recommended to avoid smoking and activities that require using great exertion for at least 24 hours before. No other special preparations are required. When cuffs will be attached and inflated, you may experience some discomfort but, generally, the process doesn’t cause physical pain.
When it is the right time to visit a doctor for pulse volume recording
PAD is characterized by the condition when the tissues of the lower extremities do not receive adequate blood and oxygen due to accumulated cholesterol that restricts normal blood flow. Let’s explore how you can spot the disease and what are the signs indicating that you have to schedule a consultation with the specialists who can perform pulse volume recording.
In the early stages, the disease may be silent without any disturbing symptoms. Later, painful sensations, cramps, or tiredness in the legs when walking may occur. The most common symptom of the damaged arteries of the lower extremities is considered intermittent claudication. It appears when you walk (when oxygen demand increases) and goes away when you are not active. As the disease progresses, you may feel pain even when walking shorter distances. Finally, in the later stages, pain may appear at rest. Without comprehensive and efficient treatment, the disease progresses steadily. Signs of this are:
- increased pain and impaired sensations in the limb, numbness, feeling of chilliness, tingling, or leg cramps;
- intense dryness and thickened skin that leads to large cracks; if left untreated, they can become infected;
- feelings of extreme weakness when walking, forcing the patient to stop and rest;
- with the progression of the disease, the pain is permanent and may deprive you of sleep.
Once you have been diagnosed with a disease, a strategic approach to improving the effectiveness of therapy to deal with vascular obstruction or narrowing should be comprehensive and consist of the correction of risk factors for the progression of atherosclerosis, sufficient walking and physical activity, as well as drug therapy.
