WebBackground: During the physiological course of pregnancy maternal peripheral vascular resistance decreases. Using the Doppler technique, the decreasing resistance and disappearance of the early diastolic notch in the arterial uterine perfusion can be observed. These changes in the Doppler flow velocity wave form are caused by the … Webwaveform shows a steep systolic slope, an early diastolic notch and a small amount of diastolic flow. The waveform is essentially a high resistance form in the non-pregnant state. As the pregnancy progresses, there is gradual removal of the notch and an increase in the diastolic flow, as seen by the fall in resistance index (RI) (4).
