WebReductions in functional residual capacity predispose patients to atelectasis. If closing capacity is higher than functional residual capacity, the alveoli in dependent regions of the lung collapse on expiration. This occurs during normal tidal breathing, trapping air and precipitating atelectasis. 41 WebThe closing volume is the lung volume at which airways start closing and the closing capacity is the sum of closing volume and residual volume. Both can be measured by the single breath N 2 washout after 100% oxygen inhalation as a distinct phase IV ( … WebSep 16, 1999 · The subject was instructed to take a deep breath from functional residual capacity to total lung capacity just after a 133 Xe gas bolus (1.5 mCi) was injected into the delivery system in the supine position and then to breathhold for 20 s for the counting of radioactivity.
