WebbLow velocity blood flow occurs mainly in small veins, venules, and capillaries. The minimum detectable flow velocity is inversely dependent on the ultrasound frequency; when using a 2.5 MHz probe, the minimum detectable flow velocity is 1.5 cm/s. In addition, commercial Doppler devices are typically limited to the frequency below 15 MHz; the ... WebbBy lowering your filter you are telling the system to listen to slower flow vs. the defaulted faster flow setting Look at the monitor and find the scale or PRF For venous insufficiency, lower the scale to capture the slow laminar flow found in the superficial vein but not so low that the color flow bleeds outside of the vessel wall fitbit 2 displays wrong time
