Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The overall purpose of this study is to evaluate maternal-fetal tissue light scattering properties. The objectives of the study are: (i) integrate established mathematical principles of oxygen saturation to model with increasing accuracy the "body in a body" problem of fetus in mother; similar to existing pulse oximeters, the calculations will be integrated into software in the final commercial product; (ii) obtain human measurements against which both computational models and animal data can be compared.
