What happens to vital capacity in geriatric patients?

In geriatric patients, vital capacity decreases significantly as part of the natural aging process. This decline can be attributed to a variety of factors, including the loss of elastic recoil of the lungs, a decrease in the strength of respiratory muscles, and the stiffening of the thoracic cage. As a person ages, their lung tissue may become less compliant, and the overall efficiency of the respiratory system diminishes. The decline in vital capacity can lead to an increase in the risk of respiratory issues, making it essential for healthcare providers to be aware of these changes in their older patients. Understanding this aspect of aging can help in planning appropriate interventions and treatments for geriatric patients.
