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.
In older individuals atelectasis may be the result of airway obstruction, as by secretions or a tumor (called obstructive, absorption, or acquired atelectasis); or it may be from a failure to deep breathe, such as postoperatively or because of neuromuscular disease.
