WebFigure 5. Hepatic vein waveform on doppler ultrasonography. A. Normal triphasic waveform is composed of two forward flows and one reverse flow. B. In patients with liver cirrhosis and portal hypertension, abnormal flat hepatic vein waverform (monophasic pattern) is observed. WebFeb 26, 2024 · An ABI ratio between 0.9–1.4 that is correlated with a multiphasic waveform (e.g., triphasic or mild biphasic) is consistent with a patient who does not have arterial occlusion. An ABI between 0.7–0.9 should correlate with biphasic waveforms (e.g., mild or weak biphasic). These waveforms have a sharp upstroke to the peak and one pit.

The second phase lasts 5-9 days, and the third phase lasts 5-10 ... Webis triphasic with normal reversal pattern and clear spectral window, while the waveform distal to a significant stenosis or occlusion often becomes biphasic or monophasic with reduced velocities and can be indicative of significant proximal aortoiliac lesion. A monophasic and dampened signal can be obtained proximal as well as distal to occlusion. gerhards the kitchen \u0026 bath store

Three combinations of birth control pills that contain progestin and estrogen are 1) monophasic, 2) biphasic, and 3) triphasic. Birth control pills may also be prescribed to reduce menstrual cramps or prevent anemia.

The waveform should be triphasic, corresponding to the three phases of a heart beat (systole, diastole, elastic recoil). Biphasic waveform indicates mild to moderate disease and monophasic flow indicates significant disease. gerhards the kitchen \\u0026 bath store
