Peak Workload as Predictor of Respiratory Complications in Patients Undergoing Resection for Lung Cancer

Wpeak ≤52% of predicted was associated with increased risk of postoperative complications and longer hospitalization. Although the discriminatory ability was modest (AUC 0.59), Wpeak ≤52% predicted was associated with higher postoperative complications and may serve as a complementary tool for risk stratification, especially in resource-limited settings. Further prospective validation is warranted.
