What change in pulmonary function is typical for geriatric patients?

In geriatric patients, an increased residual volume is common due to several age-related changes in the respiratory system. As individuals age, the elasticity of lung tissue decreases, leading to less efficient emptying of the lungs during exhalation. Consequently, more air tends to remain in the lungs after exhaling, which is referred to as increased residual volume.

Additionally, the aging process often results in changes to the chest wall and respiratory muscles, making it more difficult for these patients to fully exhale. This can compound the issue of residual volume, making it a significant consideration in the assessment of pulmonary function in older adults.

Understanding this change is crucial for healthcare providers, as it can influence how sedation is managed in geriatric patients, given their unique respiratory dynamics.
