Abstract
Methods and systems for determining collateral ventilation are disclosed. Methods may comprise introducing a diagnostic catheter into a lung compartment via an assisted ventilation device, inflating the occluding member to isolate the lung compartment, and performing a diagnostic procedure with the catheter while the patient is ventilated via the assisted ventilation device. The diagnostic procedure comprises determining an exhaled volume from the isolated lung compartment over a predetermined period of time while the patient is ventilated via the assisted ventilation device. The presence collateral ventilation may be determined based on the exhaled volume from the isolated lung compartment over the predetermined period of time.
