Predicted inspiratory capacity chart

WebBackground: Vital Capacity (VC) is defined as a change in volume of lung after maximal inspiration followed by maximal expiration is called Vital Capacity of lungs. It is the sum of tidal volume, inspiratory reserve volume .and expiratory reserve volume. Vital capacity of normal adults ranges between 3 to 5 litres. WebSep 3, 2024 · Total lung capacity (TLC) is the volume of air in the lungs at the end of maximal inspiration. The sum of RV and VC or FRC and inspiratory capacity (IC) equals TLC, which is the gold standard for diagnosing restrictive lung disease. TLC less than 80% predicted is diagnostic of a restrictive ventilatory defect.

WebMar 24, 2024 · What to Expect. Pulmonary function tests (PFTs) are used to assess various aspects of your lung function. These noninvasive tests—spirometry, the lung diffusion test, and lung plethysmography—are used to help diagnose lung diseases like COPD, as well as to determine how treatment is working and if such a condition is progressing. Webinterest is that of inspiratory capacity (IC) which is the maximum volume of air that can be inspired from the end of quiet expiration (functional residual capacity [FRC]) to total lung capacity (TLC).
