Pulse-Volume Recording (PVR) is a non-invasive vascular test in which blood-pressure cuffs and a hand-held ultrasound device (called a Doppler or transducer) are used to obtain information about arterial blood flow in the arms and 腿.

pvr的类型

There are several types of PVRs, including:

踝肱指数(ABI)
The ABI is a measurement of the blood pressure in the lower leg compared to the blood pressure in the arm. Your physician will compare the two numbers to determine your ABI. Normally, the blood pressures in your ankle and arm should be about equal. But if your ankle pressure is half your arm pressure (or lower), it could be a sign that your leg arteries are narrowed.

The blood pressure cuffs are placed on the arm and leg and inflated, while the Doppler is used to listen to the blood flow in the leg and arm. The ABI helps your physician diagnose arterial disease in the 腿, but it does not identify which arteries are blocked.

运动测试PVR
During the exercise testing PVR, the patient walks on a treadmill to try to reproduce the symptoms he or she has experienced. 然后, the blood pressure cuffs are placed on the patient's arms, 腿, 大腿, 脚踝, 小腿和脚. The blood pressures are measured again to determine the location of the potential blockage or narrowed area.

胸廓出口测试
During thoracic outlet testing, blood pressure cuffs are placed on the patient's upper arms. The test is performed while the patient is sitting in a chair. The technologist will move the patient's arms in different positions and take a blood pressure measurement at each position.
