WebMar 13, 2024 · Lung compliance can be calculated by dividing volume by pressure. Factors affecting lung compliance include elasticity from the elastin in connective tissue and surface tension, which is decreased by surfactant production. Lung compliance participates in the lung-chest wall system by opposing the outward pull of chest wall compliance. WebUltimately, the end result of reduced chest wall compliance and ineffectiveness of the diaphragm is diminished tidal volume that leads to a reduction in ventilation. Although alveolar dead space is unchanged, the ratio of dead space to tidal volume (V d /V t) is increased as a result of the decreased tidal volumes. Most patients with ... Web6. Decreased lung compliance and elasticity, decreased chest wall compliance, and a decline in respiratory muscle strength are age-related alterations that have an impact on respiration. These modifications may result in breathing problems, a decreased capacity for exercise, and a higher risk of respiratory infections. 7. dewey beach dogs on beach
