What are the effects of decreased mobility on respiratory system?

Decreased mobility can lead to impaired respiratory function due to reduced lung expansion and decreased airflow, resulting in shallow breathing and diminished gas exchange. It may also increase the risk of respiratory complications, such as atelectasis (collapse of lung tissue) and pneumonia, due to stagnant secretions and reduced ciliary function. Additionally, inactivity can weaken respiratory muscles, further compromising respiratory efficiency and overall lung health.
