Abstract
This document discusses, among other things, systems and methods for measuring the dynamics of pulmonary congestion in heart failure subjects over time to monitor the subjects susceptibility to pulmonary edema, including sensing and receiving information indicative of a bodily pressure and information indicative of pulmonary fluid, and using the transient responses of these measurements to compute parameters related to the dynamics of thoracic fluid accumulation, such as a critical pressure (Pc), a critical time (Tc), or a filtration index (Kfi).
