Resting hyperinflation
Did you know?
WebStatic hyperinflation, defined as an increased volume of air remaining in the lung at the end of spontaneous expirations, is present when resting functional residual capacity (FRC) or end expiratory lung volume (EELV) are increased above normal. It is caused by entrapment of air during expiration. 10.

WebJul 25, 2024 · With late progression of COPD, patients can develop hyperinflation of the lungs, a complication that results in shortness of breath with exertion or at rest. For patients with COPD, the residual volume/total lung capacity ratio (RV/TLC ratio) greater than 40% is a predictor of resting hyperinflation and an independent risk factor for all-cause mortality.
