Description: WEBMar 19, 2023 · No difference in average Montevideo units was found between women who delivered vaginally and those who had a cesarean delivery. Some women who delivered vaginally never achieved a contraction pattern of ≥200 Montevideo units (43.9% nulliparous and 46.6% multiparous women), and similar labor patterns were observed in …

Description: WEBMontevideo units are calculated by subtracting the baseline uterine pressure from the peak contraction pressure for each contraction in a 10-minute window and by adding the pressures generated by each contraction. In the example shown, five contractions occurred, producing pressure changes of 52, 50, 47, 44 and 49 mm Hg, respectively. ...

Description: WEBSep 19, 2022 · A thin catheter is inserted into the uterus and monitors changes in pressure. The standard unit of measurement is the Montevideo unit (MVU). Adequate contractions are defined as a total of 200 MVU within 10 minutes. Internal monitoring has limited use because it requires the rupture of fetal membranes for placement.
