It also offers the feature of instantly jumping to the required part of the program without having to fast forward or rewind. Most often, PVR is offered as a part of the subscriber service with or without monthly fees.

Full Form of PVR – Pulse Volume Recording
PVR Full Form is Pulse Volume Recording. PVR is a vascular test of non-invasive nature that is used for obtaining information regarding the arterial flow of blood in the legs and arms. Here, the term non-invasive means that no needles, radiation, dyes, or anesthesia are used for doing this test. A transducer or a Doppler, which is a handheld device, and blood pressure cuffs are used for the PVR study. These two devices determine the general location, severity, and presence of the arterial occlusive disease. Another name of the PVR is the Doppler pressure study or vascular study.
PVRs are of several types. The three main types are the ABI or Ankle Brachial Index, Exercise Training PVR, and Thoracic Outlet Testing. In the ABI, a measurement of the comparison between the blood pressures in the arm and lower leg is made. The ABI is determined by the physician by comparing these two numbers. In normal cases, the blood pressures in arm and ankles are nearly equal. In case the value of the ankle pressure is nearly half or lower than that of the arm pressure, then it may indicate the narrowing of the patient’s leg arteries.
The blood pressure cuffs are wrapped around the leg and arm and then inflated. On the other hand, the blood flow in the arm and leg is listened by using the Doppler. The ABI is used for diagnosing arterial disease in the patient’s legs, but it cannot identify the blocked arteries. In the Exercise Testing PVR, the blood cuffs are wrapped around the feet, ankles, legs, calves, and thighs while the patient walks on the exercise equipment, like a treadmill. The Thoracic Outer Test is done while the person is sitting. The test takes approximately thirty to ninety minutes to finish. The PVR does not have any side effects on the patient. The reason for this is that no radiation is used as other X-ray tests do.
