Atelectasis fever decreased as the incidence of atelectasis increased. A recent review article summarizing the available published evidence on the association between atelectasis and post-op fever concluded that there is no clinical evidence supporting this doctrine. The most common cause is post-surgical atelectasis, characterized by splinting, i.e. restricted breathing after abdominal surgery. Another common cause is pulmonary tuberculosis. Smokers and the elderly are also at an increased risk.
