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 is adapted to predict an occurrence of impending thoracic fluid accumulation using the one or more thoracic fluid accumulation prediction criteria and the at least one thoracic fluid accumulation parameter.

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.
