  • (a) acquiring flow data and volume data, wherein flow data relates to a rate of air flow into and out of the patient'"'"'s lungs and volume data relates to changes in volume of the patient'"'"'s lungs;

    (b) generating a flow/volume loop based on at least some of the flow data and at least some of the volume data, the flow/volume loop having an expiration portion and an inspiration portion, the expiration portion beginning with a full-inhale point and ending with a full-exhale point, which both lie along a zero-flow line; and

    (c) calculating an exhale pattern parameter based on an overall shape of an expiration space, which is bounded by the expiration portion of the flow/volume loop and the zero-flow line.
