Atelectasis

Overview

Atelectasis is the collapse or incomplete expansion of part or all of a lung, causing loss of lung volume. It may result from airway obstruction, compression, or reduced surfactant, leading to impaired gas exchange.

Symptoms

• Shortness of breath
• Chest tightness
• Cough
• Cyanosis

Treatment

Address the underlying cause to relieve airway obstruction, encourage deep breathing and expectoration, and perform bronchoscopy or surgery when needed.

Dietary advice

Eat a high-protein nutritious diet and drink plenty of water to help clear sputum.
