Design outcomes

Primary

Measure	Time frame
Primary outcome is the evaluation of the micro-bubble activity after stopping the heart-lung machine. The micro-bubbles are measured during CPB with the bubble counter Gampt BCC200. The numbers and the volume of the micro air bubbles before and after the oxygenator oxygenator/ the dynamic bubble trap are measured to compare the efficiency of the arterial filter and the dynamic bubble trap.	—
