Pvr tests are a type of examination that measures the movement of blood inside vessels, to say more exactly, they check the liquid speed and the character of flow. Such studies make it possible to find out whether a person has inner disorders, for example, peripheral artery disease. Doctors track pulse volume recordings, analyze them and prescribe curing that helps eliminate the symptoms. This hallmark is especially effective for diabetics who more often have similar disarrays. The principle of such examination has enough advantages, therefore, specialists use it for rectification of the diagnosis.
Positive sides of PVR test

Certainly, a specialist looks at different factors such as blood pressure, ankle-brachial index, the shape of waves. The set of data forms the general picture which an expert implements. The significant point is comparing the pressure on both legs.
Regularity of the PVR test
