Background Atelectasis results in impaired compliance and gas exchange and, in extreme
cases, increased microvascular permeability, pulmonary hypertension, and right ventricular …

Development of atelectasis is common in both patients with and without lung injury during
mechanical ventilation. Atelectasis might contribute to or attenuate lung injury by different …

Atelectasis occurs in the dependent parts of the lungs of most patients who are anesthetized.
Development of atelectasis is associated with decreased lung compliance, impairment of …

Pulmonary atelectasis is common in the perioperative period. Physiologically, it is produced
when collapsing forces derived from positive pleural pressure and surface tension overcome …

During anaesthesia the combination of breathing at low lung volume, the administration of
nitrous oxide and high inspired oxygen concentrations produces conditions that favour …

Atelectasis in the presence of preexisting lung disease or limited cardiopulmonary reserve
may have significant consequences. Increasing understanding of the underlying nature of …

The pathophysiological basis of pulmonary atelectasis is reviewed and risk factors that
enhance lung collapse are discussed. Management strategies to reduce or eliminate risk …

Background: General anaesthesia impairs the gas exchange in the lungs, and moderate
desaturation (SaO2 86–90%) occurred in 50% of anaesthetised patients in a blinded pulse …

Background The use of 100% oxygen during induction of anesthesia may produce
atelectasis. The authors investigated how different oxygen concentrations affect the …

IMPLICATIONS: Acute respiratory failure is characterized by severe decreases in blood
oxygen. The pattern of blood flow within the lungs can contribute to this problem. This study …
