Abstract: The method is for monitoring a childbirth process of a pregnant woman. A plurality of cervix dilatation data and fetal positioning data are obtained and fed to a device. A plurality of lactate concentrations is measured at time intervals. The measured lactate concentrations are shown on a display of the device at the time intervals to show a trend of the lactate concentrations. The cervix dilation data and the fetal positioning data are also shown on the display. The lactate concentrations are evaluated to determine whether the lactate concentrations are rising to indicate that an individual lactate threshold value of the pregnant woman has been exceeded. The medical practitioner may also evaluate the cervix dilation data and the fetal positioning data.
