Fetal breathing movements and fetal distress

Twenty-seven pregnancies were monitored by antenatal cardiotocographs, daily fetal movement counts and an assessment of fetal breathing activity by real time scanning, and the results of these tests were related to the development of fetal distress during the first stage of labour. The proportion of time during which fetal breathing movements were present, determined over only a short period of time, was found to be a useful predictor of fetal behaviour during a labour.
