Comparison between a newly developed PC-based Doppler umbilical artery waveform analyser and a commercial unit

To determine the accuracy of the resistance index (RI) of flow velocity waveforms of the umbilical artery measured using a newly developed PC-based continuous wave Doppler device (Umbiflow) with regard to systematic and random variations when compared with a commercial standard (Vasoflow). A cohort...
