Title
(EN) CARDIOPULMONARY RESUSCITATION DECISION SUPPORT
(FR) AIDE À LA DÉCISION EN MATIÈRE DE RÉANIMATION CARDIO-PULMONAIRE
Abstract
(EN) According to an aspect, there is provided a system for providing cardiopulmonary resuscitation (CPR) decision support, the system comprising: a photoplethysmography (PPG) sensing unit configured to determine one or more PPG signals at a measurement site on a subject; a core unit comprising a user interface; a motion sensing unit configured to detect motions correlated to chest compressions during compression therapy on the subject; and a processing unit configured to: determine presence or absence of a spontaneous pulse based on the detected motions correlated to chest compressions during compression therapy on the subject and the one or more PPG signals; determine a recommendation to be provided based on the determination of presence or absence of a spontaneous pulse, wherein the recommendation is associated with CPR decision support; and control the user interface to output the determined recommendation.
(FR) Selon un aspect, l'invention concerne un système pour fournir une aide à la décision en matière de réanimation cardio-pulmonaire (RCP), le système comprenant : une unité de détection de photopléthysmographie (PPG) configurée pour déterminer un ou plusieurs signaux PPG à un site de mesure sur un patient ; une unité centrale comprenant une interface utilisateur ; une unité de détection de mouvement configurée pour détecter des mouvements corrélés à des compressions thoraciques pendant une compressothérapie sur le patient ; et une unité de traitement configurée pour : déterminer la présence ou l'absence d'un pouls spontané sur la base des mouvements détectés corrélés à des compressions thoraciques pendant une compressothérapie sur le patient et d'un ou plusieurs signaux PPG ; déterminer une recommandation à fournir sur la base de la détermination de la présence ou de l'absence d'un pouls spontané : déterminer la présence ou l'absence d'un pouls spontané sur la base des mouvements détectés corrélés aux compressions thoraciques pendant la thérapie de compression sur le sujet et le ou les signaux PPG ; déterminer une recommandation à émettre sur la base de la détermination de la présence ou de l'absence d'un pouls spontané, la recommandation étant associée à une aide à la décision en matière de RCP ; et commander l'interface utilisateur pour émettre la recommandation déterminée.
