Receiver operating characteristic curves for systolic pressure variation and pulse pressure variation. Receiver operating characteristic curves for (a), (b) systolic pressure variation and (c), (d) pulse pressure variation, with the four different respiratory interventions, for predicting a 15% increase in stroke volume by subsequent fluid loading. SPV 0, systolic pressure variation with no resistor; SPV I, systolic pressure variation with the inspiratory resistor; SPV E, systolic pressure variation with the expiratory resistor; SPV I/E, systolic pressure variation with the combined inspiratory and expiratory resistor; PPV 0, pulse pressure variation with no resistor; PPV I, pulse pressure variation with the inspiratory resistor; PPV E, pulse pressure variation with the expiratory resistor; PPV I/E, pulse pressure variation with the combined inspiratory and expiratory resistor; AUC, area under the curve.
