Abstract
Fetal heart rate monitors, including the newer pulse-oximetry and STAN monitors, are designed to detect fetal distress that affects less than 1% of women in labor. Non-progressive labor is a much more common disorder than fetal distress, with approximately 50% of women in labor requiring oxytocin. Current technology assessing labor progress is subjective and inaccurate. There is a need for objective and accurate technology to measure labor progress and the effect it may have on managing labor and, specifically, non-progressive labor.
