Fetal ST Segment and T Wave Analysis in Labor

The purpose of this research is to test a new instrument, called a fetal STAN monitor, that may be used during labor to monitor the electrical activity of the baby's heart. This new instrument is designed to help the doctor determine how well the baby is doing during labor. It will be used along with the existing electronic fetal monitor used to measure the baby's heart rate and the mother's contractions during birth. The specific purpose of this research study is to see if this new instrument (fetal STAN monitor) will have an impact on newborn health.

Stanford is currently accepting patients for this trial.
