Abstract:

The study discusses fuzzy ef-fects of oxygen saturation (SaO2) values obtained using spectrophotometry meas-urements during intranatal fetal monitor-ing. The measurements were taken from umbilical artery (UA) and umbilical vein (UV). The fuzzy rules describe reliability and importance of SaO2 values. This helps to produce a decision with a certain degree of warning value that helps doctors to initiate extra cautions to prevent hy-poxic conditions during intrapartum. Mothers with singleton, livebirths were included in the study (N=1537). The af-terbirth measurements were used. But it is assumed that they have indicated SaO2 values just before birth. It is verified that the local oxygen saturation information presents a fuzzy value for the indication of adverse conditions. The significance and reliability of the intranatal diagnosis were discussed.
