The present invention relates to a processor and a system (1, 1 ') for the examination of the detection of the oxygenation state of a subject (100), in particular for the examination of newborn babies of congenital heart disease . The system comprises an image forming unit (2) for obtaining a plurality of image frames of the subject (100) with respect to time, and a processor (3) for processing the image frames. The imaging unit, for example a conventional video camera as it is used in the monitoring of vital signs using the aforementioned principle of remote PPG, is used as a pulse oximeter with less contact, by means of which a body map is created (at least for some of the body parts of interest) at least of the oxygen saturation of the blood. The choice of certain areas of the body, for example, the upper right limb against the upper and / or lower left limb, and the combination or comparison of them may serve the purpose of detecting abnormalities of the functions of the heart and / or set of circuits |
