“…This caused both an increase in Qp as well as increased IVC saturations and improved systemic oxygenation. Others have documented that modestly elevating CO 2 increases cardiac output after cardiac surgery and during anesthesia (23,24), and at least one report suggests that despite an increase of 64% in cardiac output selective cerebral vasodilation does not occur (25 assumed value. In addition, the difficulties in obtaining a true mixed oxygen saturation from the IVC are well known (27).…”

We have demonstrated that after the BCPA, systemic oxygenation, Qp, Qs, and cerebral blood flow increased and SVRI decreased at CO(2) tensions of 45 and 55 mm Hg compared with 35 mm Hg. We suggest that hypoxemia after the BCPA is ameliorated by a higher PaCO(2) and that low PaCO(2) or alkalosis may be detrimental. Hypercarbic management strategies may allow earlier progression to the BCPA, which may contribute to reducing the interval morbidity in patients with a functional single ventricle.
