1. A method for reducing computational resource usage for computer-assisted lung function diagnosis, the method comprising:
- receiving, with one or more physical processors, measurements of expiratory volume of a subject during an expiration by the subject for a test;
creating a plot representing the measurements of expiratory volume of the subject;
determining, with one or more physical processors, shape templates associated with the test, wherein each of the shape templates represents expiratory volume measurements that are unreliable for the test;
determining, with one or more physical processors, whether to perform an automated interpretation process on the plot representing the measurements of expiratory volume of the subject such that;
(i) responsive to a shape representative of the plot corresponding to at least one of the shape templates associated with the test, performance of the automated interpretation process on the plot to generate a diagnosis for the subject is avoided; and
(ii) responsive to the shape representative of the plot not corresponding to any of the shape templates associated with the test, the automated interpretation process is performed on the plot by one or more physical processors to generate the diagnosis for the subject, wherein the automated interpretation process is configured to interpret expiratory volume measurements with respect to the test to generate the diagnosis, the diagnosis comprising an assessment regarding a lung function of the subject.

Abstract
Automated analysis and interpretation of spirograms is provided to assess lung function of a subject. If the shape of a spirogram plot is deemed suitably reliable, the spirogram may be subsequently used for diagnostic purposes. Quality control of spirograms and/or interpretation of reliable spirograms may use shape templates corresponding to common test problems and/or typical lung diseases.
