Figure 1 Individual and mean values of main variables of hemodynamics and oxygen transport, including total pulmonary vascular resistance inclusive of the resistance of the Blalock-Taussig shunt (BT-PVR) and systemic vascular resistance (SVR), pulmonary (Qp) and systemic (Qs) blood flows, hemoglobin value (Hb), oxygen delivery (DO2), oxygen consumption (VO2), oxygen extraction ratio (ERO2), and arterial lactate levels during the first 72 hours after arrival in the ICU. *Data were entered after logarithmic transformation. **Data were entered after polynomial transformation, with time indicating the parametric estimate of the early trend and time2 indicating the later trend.
