Brief Summary

Preterm birth refers to a delivery that occurs before 37 weeks of gestation. Identification of those who will eventually deliver in the preterm period is very important. However, few interventions have been proven to prolong pregnancy in women at risk such as cervicovaginal fetal fibronectin (fFN) level or transvaginal cervical length measurements. In a meta-analysis comparing fetal breathing with cervicovaginal fetal fibronectin (fFN) level or transvaginal cervical length measurements, absence of fetal breathing was superior to other methods for prediction of preterm birth in 48 hours or 7 days. In this study, the investigators hypothesized that if a fetus holds its breath in case of preterm birth, then there may be specific fetal breathing patterns during preterm labor, which may be detected by ultrasonography
