# Raydiant Oximetry, Inc.

> Raydiant Oximetry is a clinical-stage medical device company building Lumerah, a noninvasive, transabdominal fetal pulse oximeter that measures a baby's blood-oxygen levels during labor. By giving obstetricians a direct read on fetal oxygenation - rather than the coin-flip guesswork of conventional fetal heart-rate monitors - the company aims to cut unnecessary C-sections and reduce maternal and neonatal harm. It holds FDA Breakthrough Device designation and is partnered with GE HealthCare.
