TY - JOUR T1 - QUantitative transcutaneous arterial velocity measurements with doppler flowmeters AU - Shoor PM, Fronek A, Bernstein EF Y1 - 1979/08/01 N1 - 10.1001/archsurg.1979.01370320054009 JO - Archives of Surgery SP - 922 EP - 928 VL - 114 IS - 8 N2 - • A controlled in vitro and in vivo comparative evaluation of four Doppler ultrasonic blood velocimeters was performed to evaluate their ability to measure fluid velocity throughout a wide range of flow rates and velocity profiles, during both steady and pulsatile flow. The instruments tested were the Versatone Bidirectional Doppler M-9, the Sonicaid BV380, the Parks 806 B, and the Delalande DUD 400. All instruments responded linearly to velocities of from 5 to 70 cm/s, and were accurate to within 5% through a wide range of in vitro changes in velocity, pulse frequency, and cross-sectional velocity profile. Quantitative velocity measurements and their derivatives are an inexpensive, simple, and useful tool in the evaluation conditions of patients with peripheral vascular disease, and widespread clinical trials of their value are appropriate at this time.(Arch Surg 114:922-928, 1979) SN - 0004-0010 M3 - doi: 10.1001/archsurg.1979.01370320054009 UR - http://dx.doi.org/10.1001/archsurg.1979.01370320054009 ER -
