Functional Performance of Different Venous Limb Options in Simulated Neonatal/Pediatric Cardiopulmonary Bypass Circuits
Objective: Hemodilution is a concern in cardiopulmonary bypass (CPB). Using a smaller
dual tubing rather than a single larger inner diameter (ID) tubing in the
venous limb to decrease prime volume has been a standard practice. The
purpose of this study is to evaluate these tubing options.Methods: Four different CPB circuits primed with blood (hematocrit 30%) were
investigated. Two setups were used with two circuits for each one. In Setup
I, a neonatal oxygenator was connected to dual 3/16" ID venous limbs
(Circuit A) or to a single 1/4" ID venous limb (Circuit B); and in Setup II,
a pediatric oxygenator was connected to dual ...
