Methods and systems for endobronchial diagnostics

摘要

Methods and systems for targeting, accessing and diagnosing diseased lung compartments are disclosed. The method comprises introducing a diagnostic catheter with an occluding member at its distal end into a lung segment via an assisted ventilation device; inflating the occluding member to isolate the lung segment; and performing a diagnostic procedure with the catheter while the patient is ventilated. The proximal end of the diagnostic catheter is configured to be attached to a console. The method may also comprise introducing the diagnostic catheter into the lung segment; inflating the occluding member to isolate the lung segment; and monitoring blood oxygen saturation. The method may further comprise introducing the diagnostic catheter into the lung segment; determining tidal flow volume in the lung segment; determining total lung capacity of the patient; and determining a flow rank value based on the tidal flow volume of the lung segment and the total lung capacity.

1. A method of assessing the functionality of a lung segment of a patient, the method comprising:
introducing a diagnostic catheter into the lung segment, wherein the diagnostic catheter comprises a distal end comprising an occluding member and a proximal end configured to be attached to a console; determining tidal flow volume in the lung segment; determining total lung capacity of the patient; determining a flow rank value based on the tidal flow volume of the lung segment and the total lung capacity; and determining a treatment option based on the flow rank value, wherein at least the tidal flow volume and the total lung capacity are displayed on the console.
