Scatter plot of measured and expected MAP after fluid bolus.
Scatter plot comparing measured and expected MAP after fluid bolus. Line represents perfect fit. MAP = Mean arterial pressure.

Scatter plot of measured and expected UO one hour after fluid bolus.
Scatter plot comparing measured and expected UO one hour after fluid bolus. Line represents perfect fit. UO = Urine output.

Fig 4.
Boxplot of difference between measured and expected MAP by indication for bolus.
Boxplot showing difference between expected and measured MAP by main reason for administration of fluid bolus. Positive values indicate a higher value for expected MAP compared to measured, and the inverse for negative values. MAP = Mean arterial pressure. CVP = Central venous pressure. ScvO2 = Central venous oxygen saturation. ScvO2 = Mixed venous saturation.
