  • Method and apparatus for predicting material hypertension during pregnancy using coherence analysis of material and fetal blood velocity waveforms
    Patent number: 7374539
    Abstract: An embodiment of a method of predicting maternal hypertension during pregnancy is disclosed. The method may include measuring a maternal blood velocity waveform and measuring a fetal blood velocity waveform. The method may further include the calculation of a coherence value using a magnitude-squared coherence function between the maternal and fetal blood velocity waveforms and comparing the coherence value to a predetermined threshold value.
