Closing capacity lunge
WebClosing capacity is the volume of gas within the lungs at the point at which airways closure begins. It is the sum of closing volume and residual volume. These values can be … WebAs the lung volume is reduced towards RV, there is a point at which dependent airways begin to close, and the lung volume at which this occurs is known as the closing capacity (CC). The alternative term, closing volume, equals the closing capacity minus the RV (Fig. 3.6). Closing capacity increases linearly with age and is less than FRC in ...
