Noninvasive method to find oxygen saturation of the fetus using photoplethysmogram

Abstract

This is a survey paper done on all the methods which are trying to measure oxygen saturation of the fetus using PPG signal non invasively. Lack of oxygen in the baby's blood can result in brain damage and, in the worst cases, death. Although every unborn child has a reserve supply of oxygen (oxygen margin of safety) to draw upon during labor, exactly how… (More)
