An Interactive Dive Into Pulmonary Function Testing Interpretation

---

1.  What values cannot be directly measured during spirometry? RV and TLC FEV1 and FVC FEV1/FVC ratio PEFR and FEV1/FVC ratio

2.  What value is measured specifically during a complete (full) PFT? FVC FEV1 FRC FEV1/FVC ratio

3.  How can spirometry results be beneficial for chronic disease management and patient education? Evaluates the degree of impairment Detects pulmonary disease Provides surveillance of occupational lung diseases All of the above

4.  What is an estimate of the mathematical difference between TLC and RV? Vital Capacity Tidal volume Functional Residual Capacity Inspiratory Reserve Volume

5.  In a restrictive disease, is the volume of expiration greater when compared to an individual with normal expiration? No, the volume decreases No, the volume stays constant Yes, the volume increases None of the above
