Pulse Volume Recording (PVR) is a non-invasive diagnostic test used to assess blood flow and detect blockages in the arteries, particularly in the extremities. It measures changes in volume within the blood vessels with each heartbeat, helping to evaluate the presence and severity of peripheral artery disease (PAD).

Pulse Volume Recording

Non-invasive Diagnostic Test

Blood flow refers to the movement of blood through the circulatory system, driven by the heart's pumping action and regulated by blood vessel constriction and dilation. It is essential for delivering oxygen and nutrients to tissues and organs while removing waste products, maintaining homeostasis and supporting overall health.

Changes in volume

Blood vessels are integral components of the circulatory system that transport blood throughout the body, ensuring the delivery of oxygen and nutrients to tissues and the removal of waste products. They are classified into three main types: arteries, veins, and capillaries, each serving distinct functions in maintaining circulatory efficiency and homeostasis.

Peripheral Artery Disease (PAD) is a common circulatory problem where narrowed arteries reduce blood flow to the limbs, often causing leg pain when walking. It is a significant marker of systemic atherosclerosis and is associated with an increased risk of cardiovascular events and mortality.
