In pulmonary function testing, what does FVC stand for?

• A. Forced Vital Capacity
• B. Functional Vital Capacity
• C. Forced Expiratory Volume
• D. Forced Vital Capacity

Answer: (D)

FVC stands for Forced Vital Capacity—the maximum amount of air you can forcibly exhale after taking a full, deep breath. The emphasis is on a rapid, maximal exhale, which is why it’s “forced,” and on the total volume moved during that maneuver, which is the “vital capacity.” This distinguishes it from terms like Functional Vital Capacity (not a standard measurement in this test) and from Forced Expiratory Volume (which refers to the amount expelled in a specific time, such as the first second, not the total exhaled volume). So the correct choice reflects the complete volume exhaled during a forced maneuver.
