Fetal breathing movements occur in uncomplicated gestations. The relationship of fetal breathing movements recorded in 30 min sessions to gestational age and blood glucose levels is described. A total of 142 recording sessions were obtained from 45 gravid women with uncomplicated pregnancies from 24 to 41 weeks' gestation. There was a significant increase in the proportion of time spent in fetal breathing as gestational age increased. Glucose levels in a normal range (70 to 120 mg/100 ml) at the time of the recording sessions showed no correlation with the proportion of fetal breathing time.
