Abstract:
The disclosure is directed to intrapleural air leak detection and monitoring. According to various embodiments of the disclosure, an air leak may be detected utilizing at least one sensor to determine whether fluid extracted from a pleural cavity of a patient includes carbon dioxide and/or a second substance. The second substance may be a foreign substance inhaled by the patient to confirm presence of the air leak. The air leak may be further monitored over a period of time by collecting temporally successive measurements associated with detected concentrations of carbon dioxide. Therefore, tissue damage and recovery may be assessed according to objectively collected criteria.

Claim (Index 8):
A system for monitoring pleural fluid, comprising:\n at least one detection unit configured to receive fluid from a pleural cavity of a patient, detect carbon dioxide present in the fluid, and detect a second substance present in the fluid; at least one processing unit in communication with the at least one detection unit, the at least one processing unit configured to provide a first electrical signal when the at least one detection unit detects carbon dioxide, and provide a second electrical signal when the at least one detection unit detects the second substance; a user interface in communication with the at least one processing unit, the user interface configured to provide a first indication when the first signal is received from the at least one processing unit, and provide a second indication when the second signal is received from the at least one processing unit; and an adaptor fluidically coupled to a chest tube, the adaptor configured to direct a first portion of fluid received from the chest tube along a detection path to the at least one detection unit, and further configured to direct a second portion of the fluid received from the chest tube along a drainage path to a fluidically coupled drainage canister.
