Abstract Method for determining at least one parameter that is suitable as a basis for identifying high risk pregnancies and System for identifying high risk pregnancies The invention relates to a method for identifying high risk pregnancies comprising the step of generating a spectrogram from of the doppler ultrasound signals reflected from the uterine artery and determining the maximum frequency envelope of said spectrogram, and defining a systolic and a diastolic portion of the maximum frequency envelope and calculating an area ratio under said systolic and diastolic portion (air). This area ratio refers to the blood volume in the uterine artery. The invention also relates to a system and software product that implements the method. 1/1
