Analysis of the receiver operating characteristics curve. Analysis of the receiver operating characteristic curve (100 – sensitivity versus specificity) for the ratio between maximal volume hysteresis and total lung capacity (MH/TLC) using 40% increase in end-expiratory lung volume (EELV), 40% increase in compliance of the respiratory system (Crs), 20% decrease in partial pressure of arterial CO₂ (PaCO₂) and 30% increase in partial pressure of arterial oxygen (PaO₂).
