Figure 1

Schedule of measurements. Respiratory rate (RR), minute ventilation (VE), arterial carbon dioxide tension (PaCO2) and mixed venous carbon dioxide tension (PvCO2) were recorded both at the end of the normal breathing period (NB) and at the end of the partial rebreathing period (RB). At the middle of normal breathing period cardiac output using partial carbon dioxide rebreathing technique (CONI) was measured; then, cardiac output using thermodilution technique (COTD) was measured in triplicate and the values were averaged.
