Sciurba,Cooper,and Trulock proposed three hypotheses to explain improvements in symptoms and pulmonary function.The hypotheses include the following:(1)surgery causes an increase in elastic recoil of the lung creating greater efficiency in respiratory muscle and chest wall mechanics;(2)beneficial effect on the mechanical function of musculoskeletal components by reducing the functional residual capacity allowing the muscles to work at a more optimal length;and (3)the decrease in hyperinflation and normal cardiac filling is possible.
