Vital capacity is the maximum amount of air a person can exhale after taking a deep breath, and residual volume is the amount of air left in the lungs after a maximal exhale. With a reduced vital capacity and increased residual volume, the older adult may have difficulty taking deep breaths and fully exhaling, leading to shallow breathing. This can also lead to ineffective coughing, as the person may not be able to generate enough force to clear secretions from the airways. Slow respiratory rate and frequent respiratory infections are not necessarily associated with these changes in pulmonary function.
