Montevideo units
（重定向自Montevideo unit）
Montevideo units are a method of measuring uterine performance during labor. They were created in 1949 by two physicians, Roberto Caldeyro-Barcia and Hermogenes Alvarez, from Montevideo, Uruguay.
Units are calculated by internally (not externally) measuring uterine pressure above baseline tone and multiplying by the number of contractions in a 10-minute period. Uterine pressure is generally measured through an intrauterine pressure catheter.
