Pulmonary Function Tests (PFTs) | Examples 1 & 2

The video tutorial explains pulmonary function tests, focusing on differentiating between restrictive and obstructive pulmonary defects. It covers key spirometry values like FVC, FEV1, and DLCO, and their roles in assessing lung function. The tutorial provides examples to illustrate how to analyze these values to identify restrictive or obstructive defects, and discusses intrinsic and extrinsic restrictive defects, as well as the implications of gas exchange impairment.
