Title
(EN) APPARATUS AND METHOD AND COMPUTER PROGRAM PRODUCT FOR DETERMINING A BLOOD PRESSURE MEASUREMENT
(FR) APPAREIL ET PROCÉDÉ ET PRODUIT DE PROGRAMME INFORMATIQUE POUR DÉTERMINER UNE MESURE DE PRESSION ARTÉRIELLE
Abstract
(EN) There is provided an apparatus (100) for determining a blood pressure measurement for a subject (102). The apparatus (100) comprises a processor (104) configured to acquire, from a light sensor (106), measurements of an intensity of light (108) of a first wavelength range reflected from the skin (110) of the subject (102) for a range of forces at which the light sensor (106) is applied to the skin. The processor (104) is further configured to determine a pulse amplitude from the measurements of light intensity at the range of applied forces and analyze the determined pulse amplitudes to determine a systolic blood pressure measurement based on the applied force at which the pulse amplitude drops below a predefined threshold and/or an integral of the pulse amplitudes and/or a diastolic blood pressure measurement based on the applied force at which an initial rise in the pulse amplitude is identified.
(FR) L'invention concerne un appareil (100) pour déterminer une mesure de pression artérielle pour un sujet (102). L'appareil (100) comprend un processeur (104) configuré pour acquérir, à partir d'un capteur de lumière (106), des mesures d'une intensité de lumière (108) d'une première plage de longueurs d'onde réfléchie par la peau (110) du sujet (102) pour une plage de forces auxquelles le capteur de lumière (106) est appliqué sur la peau. Le processeur (104) est en outre configuré pour déterminer une amplitude de pulsation à partir des mesures d'intensité de lumière au niveau de la plage de forces appliquées et analyser les amplitudes de pulsation déterminées pour déterminer une mesure de pression artérielle systolique sur la base de la force appliquée à laquelle l'amplitude de pulsation chute au-dessous d'un seuil prédéfini et/ou une intégrale des amplitudes d'impulsion et/ou une mesure de pression artérielle diastolique sur la base de la force appliquée à laquelle une élévation initiale de l'amplitude de pulsation est identifiée.
