Webb29 jan. 2024 · As a rough guideline, the normal predicted FEV1 in a 50-year old of average height is about 4.0 L for a male and 3.0 L for a female. It can be generalized that patients with severe obstructive disease will have a FEV1 of less than 1 L, while those with moderate disease may have values of 1.0–1.5 L. Forced Vital Capacity (FVC) WebbA decreasing Dlco is superior to following changes in slow vital capacity (SVC) or TLC in ILDs. Dlco is a specific but insensitive predictor of abnormal gas exchange during exercise. Low Dlco less than or equal to 50% predicted can predict hypoxemia with exercise. A normal Dlco does not rule out oxygen desaturation with exercise.

WebbVital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume. It is approximately equal to Forced Vital Capacity (FVC).

In 2005, vital capacity (VC) was described by the American Thoracic Society/European Respiratory Society (ATS/ERS) as the volume of air mobilized between a maximal inspiratory maneuver and a maximal expiratory maneuver. An FVC maneuver or a slow vital capacity (SVC) maneuver can be used in order to determine VC.
