Title (EN) APPARATUS AND METHOD FOR MEASURING THE BLOOD OXYGEN SATURATION IN A SUBJECT'S TISSUE
(FR) APPAREIL ET PROCÉDÉ DE MESURE DE LA SATURATION EN OXYGÈNE DU SANG DANS UN TISSU D'UN SUJET
Abstract:
(EN) An apparatus and a method for non-invasively determining the blood oxygen saturation within a subject's tissue by near-infrared spectroscopy use the multi-distance method and take into account the attenuation of the light signal due to light absorbers other than hemoglobin and deoxyhemoglobin and the scattering properties of a subject's tissue. The apparatus and the method are particularly adapted for the measurement of blood oxygen saturation in the abdomen of newborns taking into account meconium, transitional stool and biliverdin.
(FR) L'invention concerne un appareil et un procédé de détermination non invasive de la saturation en oxygène du sang dans le tissu d'un sujet par spectroscopie de proche infrarouge qui utilisent le procédé à distances multiples et prennent en compte l'atténuation du signal lumineux due aux absorbeurs de lumière autres que l'hémoglobine et la désoxyhémoglobine et aux propriétés de diffusion du tissu d'un sujet. L'appareil et le procédé sont particulièrement adaptés à la mesure de la saturation en oxygène du sang dans l'abdomen de nouveau-nés tenant compte du méconium, des selles en transit et de la biliverdine.
