Extracorporeal Volume
The tubing and separation channel form the extracorporeal circuit to and
from the donor/patient. The tubing configuration minimizes extracorporeal
volume. Each disposable tubing set holds less than 285 mL of whole blood
equivalent. The AutoPBSC disposable tubing set holds an extracorporeal
volume of less than 165 mL, making it suitable for use with pediatric
patients.
