Abstract: The present invention relates to systems and methods for measuring and monitoring physiological changes in a body. More particularly, the invention relates to systems and methods for measuring and monitoring the environment in the vicinity of the lung.

Abstract: The system and method may measure and monitor physiological changes in a body. In some embodiments, the system and method may measure the impedance at a site in the body. In some embodiments, the system and method identify, quantify, and localize leaks from a site following surgery. In an embodiment, the system includes a flexible conduit with one or more sensors. A flexible conduit shape may be selected to facilitate monitoring of physiological changes in a body and/or detection of leaks at a desired site. In an embodiment, contrast solution may be ingested by, injected in, and/or delivered to a patient. If a leak is present at a site, salt contrast solution may leak from a site and be detected by sensors in a flexible conduit.
