Can residual volume be measured by spirometry
There is no way to measure residual volume directly, but it can be calculated indirectly with a pulmonary function test. Other lung volumes and capacities must first be measured directly, usually with spirometry, before RV can be calculated. The first step in calculating RV is to determine the functional residual capacity … See more Residual volume is determined by two competing factors. 1. The strength of the expiratory muscles and the inwards pull of the lungs tends to decrease residual volume. 2. The … See more The lungs are never completely empty; there is always some air left in the lungs after a maximal exhalation.
