Fiber-based frequency-modulated continuous-wave near-infrared spectroscopy for transabdominal fetal pulse oximetry

Abstract

We propose a novel non-invasive approach to transabdominally measure fetal oxygen saturation via time-domain near-infrared spectroscopy. We employ the frequency-modulated continuous-wave technique to measure the time-resolved reflectance of near-infrared light shining on the maternal abdomen. The time-of-flight reflectance reveals path-lengths of different photons traveling through the tissue, facilitating the separation of signal from the shallow maternal layer and the deep fetal layer. Using two optical wavelengths, oxygen saturation of the fetus can be measured. This technique has the potential to improve labor outcomes by providing an important assessment of fetal health intrapartum.
