Title
(EN) PREDICTION OF THORACIC FLUID ACCUMULATION
(FR) PREDICTION DE L'ACCUMULATION DU FLUIDE THORACIQUE
Abstract
(EN) This patent document discusses, among other things, systems, devices, and methods for predicting an occurrence of impending thoracic fluid accumulation and in one example, invoking a responsive therapy, such as to prevent or minimize the consequences of the impending thoracic fluid accumulation. One example of the present systems, devices, and methods senses or receives at least one parameter that is statistically associated with impending thoracic fluid accumulation from a subject. Using such parameter(s), a probability of impending thoracic fluid accumulation is estimated. A list of parameters determines which values are recurrently sensed or received at various desired time intervals. Another example of the present systems, devices, and methods weights the sensed or received parameter value(s) to compute the probability estimate of impending thoracic fluid accumulation. A responsive preventive thoracic fluid accumulation therapy or other therapy is selected and activated using the probability estimate of impending thoracic fluid accumulation.
(FR) L'invention concerne, notamment, des systèmes, des dispositifs, et des procédés permettant de prévoir une survenue d'une accumulation imminente de fluide thoracique et, dans un exemple, de faire appel à une thérapie adaptée, pour, notamment, prévenir ou minimiser les conséquences de cette accumulation. Selon un exemple, ces systèmes, dispositifs et procédés permettent de détecter, ou de recevoir au moins un paramètre statistiquement associé à l'accumulation imminente de fluide thoracique chez un patient. L'utilisation de ce(ces) paramètre(s) permet d'estimer la probabilité d'une accumulation imminente de fluide thoracique. Une liste de paramètres détermine les valeurs qui sont détectées ou reçues de façon récurrente à différents intervalles temporels voulus. Selon un autre exemple, ces systèmes, dispositifs et procédés permettent de pondérer la(les) valeurs de paramètre(s) captée(s) ou reçue(s) pour calculer l'estimation de probabilité d'accumulation imminente de fluide thoracique. Une thérapie adaptée ou une autre thérapie de prévention de l'accumulation de fluide thoracique est choisie et activée à l'aide de l'estimation de probabilité d'accumulation imminente de fluide thoracique.
