MVU (Montevideo Units) is a measurement of uterine contraction strength, introduced by Caldeyro-Barcia et al. at the University of Montevideo in 1957. The formula sums the amplitude of each contraction (peak minus resting tone) over a 10-minute window. Educational reference ranges: Under 95 MVU: Lower range 95 to 200 MVU: Typical range 200 to 400 MVU: Higher range Over 400 MVU: Very high range Sources: - Caldeyro-Barcia R, et al.
