Abstract: A device is used to improve the standard of care for patients with physiologic or pathologic differences between regions of the lungs. Regional variations can occur between the left and right lungs, upper and lower lungs, different lobes in the lungs, or diffuse variation that does not follow a strict pattern. The device includes a method to quantify the differences between regions of the lungs. Quantification of regional variations in lung pathophysiology can be performed with a sensor, such as a pressure or gas concentration sensor, imaging scans, or alternative technology. This quantified parameter is used to regulate the gas flow to each lung region. One embodiment does this with a novel flow regulation mechanism for a double lumen endotracheal tube for compartmentalized lung ventilation where either the flow or pressure to the left and right lung can be varied with a flow regulation mechanism. The device has embedded software that is able to analyze the clinical parameters of the left and right lung in real-time, including advanced algorithms to provide improved clinical feedback to clinicians to allow them to provide the highest level of personalized and precision care to a patient.
