A forced vital capacity (FVC) maneuver requires a specific technique to ensure accurate measurement of lung volume and function. The correct technique involves taking a deep inhalation followed by a forceful exhalation until no air can be expelled. This process captures the maximum amount of air that can be expelled from the lungs after a maximum inhalation, which is crucial for evaluating lung function.

When performed correctly, this maneuver allows for a reliable assessment of both the total lung capacity and the ability of the lungs to expel air forcefully. Deep inhalation expands the lungs to their full capacity, while the forceful exhalation ensures that all the air is expelled quickly, which is essential for accurate and reproducible results. It reflects how effectively the lungs can move air and can help identify conditions like obstructive or restrictive lung diseases.

In contrast, alternatives like slow inhalation followed by gentle exhalation do not adequately capture the necessary flow rates or total volumes, and rapid inhalation and exhalation may not ensure complete lung emptying. Similarly, inhaling while counting to ten does not follow the required breathing technique for an FVC maneuver and fails to provide the necessary data for proper lung function evaluation. Thus, the specified method of a deep inhalation
