What is the role of early ambulation in pneumonia recovery?

• A. It increases the risk of pneumonia spread
• B. It has no effect on recovery
• C. It helps prevent complications such as atelectasis
• D. It prolongs hospital stay

Answer: (C)

Starting mobility early after stabilization helps keep the lungs well ventilated and clears secretions. When you ambulate sooner, deeper breaths and greater diaphragmatic movement occur, which expands alveoli and prevents collapse of parts of the lung (atelectasis). By keeping the airways open and improving secretion clearance, oxygenation is better and recovery tends to be smoother. Prolonged bed rest can worsen lung ventilation and lead to deconditioning, delaying healing. Early ambulation does not increase infection spread and is more likely to shorten hospital stay than prolong it.
