WebThe lung volumes, such as total lung capacity (TLC) and residual volume (RV), are very much dependent upon age and height. From age 20 to age 60, the RV may increase by up to … WebJun 8, 2015 · It is defined as "the volume of gas remaining in the lung after maximal exhalation", As with FRC, a high RV suggests expiratory gas trapping or bullous dead space. RV decreases with any disease that globally decreases all lung volumes, for example, idiopathic pulmonary fibrosis and obesity.
WebThe measure that could be estimated with the highest reliability was the ratio RV/TLC, an indicator of air trapping highly correlated with hyperinflation in COPD [ 6, 28 ]. FEV 1 % pred and FVC % pred were sufficient for this prediction, while the effect of anthropometric characteristics was minor, except for the difference between sexes. WebTotal Lung Capacity (TLC): The maximum volume of air your lungs can hold. A low TLC indicates restrictive lung disease, while a high TLC may be seen in patients with hyper-inflated lungs because of obstructive lung disease. Residual Volume (RV): The amount of air remaining in your lungs after a maximal exhalation.
