Quantitative segmental pulse volume recorder: a clinical tool.

Abstract

A quantitative segmental pulse volume recorder (PVR) has been described which is (1) simple, reliable, and reproducible, (2) capable of standardization, (3) easily employed by paramedical personnel, and (4) adaptable to measurements taken after exercise. The components of the electronic package have been tested in terms of frequency response, linearity, and calibration. It has been used in over 300 patients during the past two years to measure pulse volume amplitudes, pulse contours, and limb pressures. Preoperatively, the PVR provided a measure of the functional severity of the occlusive disease as well as an objective base line for later comparisons. Operative mbnitoring with the PVR can be easily carried out and was particularly valuable in patients undergoing proximal arterial reconstructions in the presence of distal occlusive disease. With this method, early postoperative limb monitoring in patients without palpable pulses can be carried out in the recovery area by nursing personnel. The PVR has contributed to the long-term follow-up study of patients with vascular disease by documenting the adequacy of arterial reconstructions, the progression of underlying disease, or the development of collateral circulation.
