Patterns of Changes in Arterial PO2 During One-Lung Ventilation: A Comparison Between Patients With Severe Pulmonary Emphysema and Patients With Preserved Lung Function

Conclusion: During OLV, oxygenation is better preserved for a longer period of time in patients with severe pulmonary emphysema as compared with patients with normal lung function. In contrast to patients without emphysema, prediction of oxygenation during OLV for the individual patient with emphysema is unreliable because of large interindividual differences.
