ABSTRACT:
An apparatus for measuring the oxygen saturation of fetuses during childbirth, using a probe, assigned to the fetal scalp, with two or four photodiodes operating at different wave lengths and a photodetector disposed in the plane of the photodiodes as parts of an optical reflection measurement portion for determining the oxygen saturation in the arterial or pulsating bloodstream, which is proportional to the ratio of oxyhemoglobin to the sum of oxyhemoglobin and desoxyhemoglobin by reflection measurement in an area, which is not subjected to a partial vacuum. Output signals of the apparatus are supplied to an evaluating pulsoxymeter over a cable connection having a plug-and-socket connector.
