Answer 2

Atelectasis is a collapsed or airless condition of the lung which may be caused by obstruction of one or more airways with mucus plugs; by hypoventilation secondary to pain or to ventilation with inadequate tidal volumes; by inadequate surfactant production; or by compression of the lung externally or the lung or bronchi by tumors, aneurysms, or enlarged lymph nodes. It is sometimes a complication following abdominal or thoracic surgery, caused by splinting. Thoracic and high abdominal surgery poses extra risks, because of the location of the incision. It occurs in pateints with chronic obstructive pulmonary disease, bronchiectasis, or cystic fibrosis, and also in those who smoke tobacco heavily. Chronic atelectasis, called middle lobe syndrome, results from compression of the middle lobe bronchus by surrounding lymph nodes.
insufficient attemps at respiration by the newborn, bronchial obstruction, or absence of surfactant (a substance secreted by alveoli that maintains the stability of lung tissue by reducing the surface tension of fluids that coat the lung).
