WebConventionally, lung hyperinflation is said to exist when the total lung capacity (TLC) is .120% of the predicted value. Marked elevation of the TLC usually means that increased lung compliance, as a result of emphysema, is a primary determinant of lung hyperinflation.

WebNov 16, 2014 · Based on the results we’ve seen in several studies we’ve decided that a decrease in IC of 0.25 L or greater is a significant change and an indication that hyperinflation is probably occurring. We use the Vt/IC ratio to help determine whether hyperinflation, when it occurs, may be causing a ventilatory limitation. WebJul 2, 2024 · During exercise, dynamic hyperinflation (DH), measured by a reduction in inspiratory capacity (IC), increases exertional dyspnea and reduces functional capacity in many patients with severe COPD. Although noninvasive ventilation (NIV) during exercise can improve exercise duration, the effect on DH is unclear.
