Clinical evaluation of a various type of artificial oxygenator

Abstract

In our department, we made use of 11 types of oxygenator, 6 were bubble type, the others were membrane type. Evaluation of oxygenator was held as follows.
1) Efficiency of gas transfer were shown to changes of PaO₂, PaCO₂ with V/Q being changed, O₂ transfer and Qp/Qt. 2) Efficiency of heat exchange 3) Platelet retension 4) hemolysis
As for platelet retension and hemolysis, membrane oxygenator were superior to bubble type.
