BACKGROUND AND AIM As the most common postoperative pulmonary complication after cardiac surgery, atelectasis is one of the most important and serious early postoperative complications and one of the most important causes of prolonged hospitalization, increased costs, and mortality rise. Therefore, the present study was aimed at specifying the frequency of atelectasis in patients following coro...

Positive end-expiratory pressure (PEEP) has been extensively utilized in the treatment of severe hypoxemia from noncardiogenic pulmonary edema. The usefulness of therapy with PEEP in the management of lobar atelectasis has not been previously stressed. Recently, we observed four patients with lobar atelectasis who failed to respond to the usual conservative measures of endotracheal suctioning a...

introduction: up to 12% of patients undergoing coronary artery bypass graft have pulmonary complications. smoking can cause a six-time increase in pulmonary complication after major surgery. the most common pulmonary changes after cabg are decrease in frc, vc and atelectasis. in this study, the effect of oral n-acetyl-cystein in reduction of severity of hypoxemia and atelectasis in current smok...

Pulmonary atelectasis is described as a state of a given region of lung parenchyma collapsed and non-aerated. This study aimed to describe the characteristics and clinical outcome of children with atelectasis, assisted by physical therapy service. This is a case report whose information was collected from records of children hospitalized at the University Hospital of Londrina/HU, in 2009. Seven...

Awake, spontaneously breathing humans sigh on average 9 to 10 times per hour. The sigh is a normal homeostatic reflex proposed to maintain pulmonary compliance and decrease the formation of atelectasis by recruiting collapsed alveoli. The induction and maintenance of anesthesia with muscle paralysis and a fixed tidal volume abolish the sigh. Without periodic sighs, patients are left susceptible...

The relationship between changes in the viscosity of sputum and the development of pulmonary atelectasis has been discussed.15 The fibers found in sputum which appear to be responsible for the viscosity are

BACKGROUND Doppler images of pulmonary vessels in pulmonary diseases associated with subpleural consolidations have been described. Color Doppler easily identifies such vessels within consolidations while spectral Doppler analysis allows the differentiation between pulmonary and bronchial arteries. Thus, Doppler helps in diagnosing the nature of consolidations. To our knowledge, Doppler analysi...
