A pulmonary diagnostic apparatus includes a personal computer including a memory for storing expected values, each representing a predicted normal level for a pulmonary function. A parameter limit file stores abnormality limits, each related to one of the expected values. A configuration file contains a plurality of degree of severity labels and numerical breakpoints between severity degrees. Finally, a statement data file contains a plurality of textual statements concerning lung functions and diseases or conditions. The three files are operatively associated with the computer. Lung function measuring equipment also is connected to the computer, whereby measured values are compared with the expected values. Based on the comparison, the computer generates an output identifying certain measured values as abnormal, and the degree of abnormality. Also, appropriate statements from the statement data file are generated as output, based upon the comparison. By selectively editing the parameter limit, configuration and statement files, the operator can cause the computer to generate an output corresponding to the operator's preferred analytical approach and syntax.
