BACKGROUND: To evaluate the clinical significance of predicting post-operative respiratory failure in patients with lung cancer using cardiopulmonary exercise test (CPET). METHODS: Before operation, 260 patients with lung cancer underwent CPET with incremental protocol. W%, VO₂%P, VO₂/kg, AT, MET, O₂ pulse, VTe, BF and VE were measured in the end of load exercise. RESULTS: (1) In patients after pneumonectomy, the values of the above indexes of CPET in the respiratory failure group were significantly lower than those in the non-respiratory failure group ( P < 0...
