WebFeb 27, 2024 · Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled from the lungs, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started. [1] WebPulmonary function testing is a group of tests that provide objective data on a patient's lung function. These tests must be interpreted within the context of the patient's history and physical examination, though their patterns can suggest different categories of respiratory disease. Look for evidence of respiratory disease when patients ...
