What happens to the respiratory if a person is bedridden?

When a person is bedridden, their respiratory function can decline due to reduced lung expansion and decreased mobility. This can lead to shallow breathing, decreased airway clearance, and an increased risk of respiratory infections, such as pneumonia. Prolonged immobility may also result in the accumulation of secretions in the lungs, further compromising respiratory health. Regular repositioning and breathing exercises are essential to mitigate these effects.
