測試版PVRs are measured with cuffs, and modern devices can measure segmental pressures and PVRs with the same set of cuffs. To measure PVRs, cuffs are inflated to 60 to 70 mm Hg. The exam typically is better tolerated by patients than segmental pressures due to lower pressure cuff inflations.

測試版A PVR study is a noninvasive 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 legs. Noninvasive means the procedure does not require the use of needles, dyes, radiation or anesthesia. The blood pressure cuffs and Doppler are used to determine the presence ...
