Slow vital capacity predicted values

Webb28 juni 2024 · The slow vital capacity (SVC) is another method to evaluate the respiratory function. Some neurologists found that the FVC% was not reflective of respiratory symptoms and the percent-predicted SVC (SVC%) was found to be higher in some patients with bulbar-onset ALS. Webb1 maj 2013 · Introduction. 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.
