Atelectasis is collapse of lung tissue with loss of volume. Patients may have dyspnea or respiratory failure if atelectasis is extensive. They may also develop pneumonia. Pleuritic chest pain may be present with certain causes of atelectasis. Diagnosis is by chest x-ray.
Hypoventilation is the most common cause of atelectasis, especially after chest surgery. Airway obstruction may be caused when something blocks a passage either inside the lung (like mucus or a foreign object) or outside of the lungs (like a tumor which press on the airway and cause obstruction).
