![]() ![]() Correlations between PaCO2 and PETCO2 in the four groups of children were carried out and the relationship of delta PCO2 to VD/VT and Qs/Qt was determined. ![]() Twenty-three children were cyanotic 14 with right to left intracardiac shunts and decreased PBF (cyanotic (D) group) and 9 with mixing lesions with normal or increased PBF (cyanotic (I) group). Eighteen children were acyanotic 9 with normal pulmonary blood flow (PBF) and normal intracardiac anatomy (normal group) and 9 with increased PBF (acyanotic group). End-tidal CO2 (PETCO2), arterial CO2 (PaCO2), mixed expired CO2 (PECO2), arterial and mixed venous oxygen contents were measured and the PaCO2 to PETCO2 difference (delta PCO2), physiologic dead space to tidal volume ratios (VD/VT) and venous admixture (Qs/Qt) were calculated in 41 anesthetized infants and children undergoing repair of congenital cardiac lesions. ![]()
