Pulse volume recording (PVR) is a useful initial test for patients with suspected lower limb peripheral artery disease (PAD). It can also be used as a predictor for critical limb ischaemia (CLI) and amputation. When arterial disease is present the contour of the waveform is seen to change: the slope is seen to flatten whilst pulse width widens. The dicrotic notch is also lost (TASC II). Pulse volume recordings are often used for localising the level of arterial disease and have been shown to be clinically useful in diabetic patients with peripheral vascular disease. Unlike ankle brachial pressure index (ABPI) measurements and segmental limb systolic pressure measurements, pulse volume recordings are not affected by calcified arteries. Thus pulse volume measurements are particularly useful in diabetic patients with calcified arterial vessels.<\/p>\n","protected":false},"featured_media":0,"template":"","tags":[],"class_list":["post-7882","m_applications","type-m_applications","status-publish","hentry"],"acf":[],"yoast_head":"\n
