Abstract

Minimally invasive systems and methods are provided for diagnosing conditions in target lung compartments. Using catheters capable of isolating the target lung compartments and measuring one or more of collateral ventilation, pressure, flow rate, and volume, conditions such as hyperinflation, compliance, gas exchange including oxygen uptake, directionality of collateral channels, blood flow, and blood flow per unit lung volume may be assessed.
