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. Webb30 okt. 2024 · Spirometry is a test of maximal effort, therefore, a slight hesitation or a delayed start can affect results, and so is one of the common mistakes when performing Spirometry. A hesitation in blowing out before the initial blast affects most spirometry test results early in the manoeuvre. Similarly, a test which is performed slowly or in a will ...
