Here is your first case: the patient is a 54-year-old man with a several month history of progressive dyspnea.

As noted in the discussion regarding the current ATS \u002F ERS approach to pulmonary function test interpretation, FEV1 is viewed in relationship to the largest of the aforementioned parameters. In this case, \u003C\u002Fp>\u003Cp dir=\"ltr\">\u003Cb id=\"docs-internal-guid-ff87fbfe-7fff-d555-33c4-6e6b237edb8a\">[00:01:00] \u003C\u002Fb>SVC is larger than FVC and FIVC. Therefore, the appropriate ratio to analyze is the FEV1 over SVC%. FEV1 over SVC% is 76%, which is greater than the lower limit of normal of 66%. We then look at the vital capacity once again in this case, \u003C\u002Fp>\u003Cp dir=\"ltr\">\u003Cb id=\"docs-internal-guid-ff87fbfe-7fff-d555-33c4-6e6b237edb8a\">[00:01:30] \u003C\u002Fb>SVC. SVC is 2.11, which is less than the lower limit of normal of 2.84. We then move on to review lung volumes, in particular TLC. TLC is 3.29, which is less than the lower limit of normal of 4.89; hence, we arrive at a diagnosis of restrictive lung disease. Finally,\u003C\u002Fp>\u003Cp dir=\"ltr\">\u003Cb id=\"docs-internal-guid-ff87fbfe-7fff-d555-33c4-6e6b237edb8a\">[00:02:00] \u003C\u002Fb>we look at the diffusing capacity and note that it is 14.85, which is less than the lower limit of normal of 22.17.
