Prediction of thoracic fluid accumulation
First Claim
1. A system comprising:
- a prediction criteria module, adapted to store one or more thoracic fluid accumulation prediction criteria;
a parameter collection device, adapted to sense or receive at least one thoracic fluid accumulation parameter that is statistically associated with impending thoracic fluid accumulation; and
a thoracic fluid accumulation prediction module, coupled to the prediction criteria module to receive the one or more thoracic fluid accumulation prediction criteria, and coupled to the parameter collection device to receive the at least one thoracic fluid accumulation parameter,wherein the thoracic fluid accumulation prediction module includes a probability processing module and a prediction processing module, the probability processing module for comparing the one or more thoracic fluid accumulation prediction criteria and the at least one thoracic fluid accumulation parameter and outputting to the prediction processing module a probability indication of the occurrence of impending thoracic fluid accumulation; and
wherein the prediction processing module generates, using the probability indication output from the probability processing module, a probability assertion that an occurrence of impending thoracic fluid accumulation will occur during a specified time after the prediction, wherein the probability assertion includes both a magnitude of the probability assertion and a defined time period during which the prediction is applicable, and wherein the probability assertion identifies which of the at least one thoracic fluid accumulation parameters contributed to the magnitude of the probability assertion.

Abstract
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.
