Known As

Atelectasis is also known as atelectasis, pressure collapse of lung due to OB anesthesia in pregnancy, and pressure collapse of lung due to obstetric anesthesia in pregnancy. This excludes atelectasis: congenital (partial) (770.5), primary (770.4), and tuberculous current disease (011.8). This applies to atelectasis, collapse of lung, and middle lobe syndrome.

Atelectasis Definition and Symptoms

Atelectasis is the complete or partial collapse of a lung or lobe of the lung. This happens because the small air sacs (alveoli) in the lungs become deflated. This is one of the most common complications after a surgery but can also be a complication of cystic fibrosis, lung tumors, chest injuries, or asthma. Symptoms include difficulty breathing, shallow breathing, coughing, and a low grade fever.
