1. A pulmonary diagnostic system comprising:

  • a multi-lumen pulmonary catheter having a proximal end and a distal end, wherein the distal end comprises an inflatable occlusion balloon configured to isolate a Iungcompartment from a remainder of the lung;

    a pulmonary diagnostic device comprising a transferring component configured to transfer fluids or gases to or from the lung,wherein the pulmonary diagnostic device is configured to receive measurement data from at least one sensor, and to coordinate the functioning of the pulmonary diagnostic device;

    a data receiving component;

    and one or more sensors disposed in or on the pulmonary catheter, said sensors generating measurement data reflecting respiratory features of the isolated lung compartment, wherein the respiratory features of the isolated lung compartment comprise pressure and flow;

    wherein the pulmonary diagnostic device further comprises an analyzing component configured to analyze the measurement data to generate processed measurement data, enable values of disease parameters reflective of an individual isolated lung compartment to be determined, and to calculate a resistance value of the isolated lung compartment based on the measurement data reflecting pressure and flow;

    wherein the pulmonary diagnostic device further is configured to coordinate the transfer of the fluids or gases between the components of the pulmonary diagnostic device and the lung, the passage of data between the sensor and the pulmonary diagnostic device, and the passage of data between the pulmonary diagnostic device and the data receiving component;

    wherein the system is configured to determine pressure and flow of the isolated lung compartment during unassisted breathing; and

    wherein the data receiving component is configured to receive the processed measurement data; and

    wherein the data receiving component comprises a visual display which is configured to simultaneously display resistance values corresponding to multiple lung compartments in visual form; and

    wherein the system is configured to rank the multiple lung compartments based on a level of disease or a need for treatment.
