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.
There are 4 primary mechanisms that can cause atelectasis. These include: Obstruction - Blockage of an airway, either from inside (for example, by a foreign body that is aspirated, or a mucous plug), or the outside (for example, by a lung cancer pressing on the airway), can result in collapse of a portion of the lung.
