Minute Ventilation-to-Carbon Dioxide Output (V˙e/V˙co2) Slope Is the Strongest Predictor of Respiratory Complications and Death After Pulmonary Resection

V˙e/V˙co2 slope is a better predictor of respiratory complications than peak V˙o2. This inexpensive and operator-independent variable should be considered in the clinical practice to refine operability selection criteria.
