Title (EN) SYSTEMS AND METHODS FOR DETERMING RESPIRATORY EFFORT
(FR) SYSTÈMES ET PROCÉDÉS POUR DÉTERMINER L'EFFORT RESPIRATOIRE
Abstract:
(EN) Systems and methods for calculating a measure of respiratory effort of a subject are provided. The measure of respiratory effort may be calculated based on a differential pulse transit time (DPTT) calculated for received photoplethysmograph signals. The systems and methods may allow for the calculation of respiratory effort in absolute units, and without the need for calibrations from a device that measures blood pressure (e.g., a non-invasive blood pressure cuff).
(FR) La présente invention concerne des systèmes et des procédés pour calculer une mesure de l'effort respiratoire d'un sujet. La mesure de l'effort respiratoire peut être calculée sur la base d'un temps de transition d'impulsion différentielle (DPTT) calculé pour des signaux de photopléthysmographe reçus. Les systèmes et procédés peuvent permettre le calcul de l'effort respiratoire en unités absolues, et sans nécessiter les calibrages d'un dispositif qui mesure la pression artérielle (par exemple, un manchon de pression artérielle non invasif).
