Tygon" Roller Pump Tubing

A failure analysis was performed on Norton S-65-HL Tygon® tubing. Fatigue testing was performed on four sizes of this tubing, and essentially showed how the tubing wears out. A dynamic "life hours to failure" test, which was performed on the 3/8" internal diameter (ID) size, quantified when the tubing ruptured. Based on results of laboratory testing and the institution's clinical extracorporeal membrane oxygenation (ECMO) experience, a reasonable life expectancy for the 3/8" S-65-HL Tygon® size was determined for use in this institution's neonatal ECMO system. An understanding of the expected performance of roller pump tubing an integral component of the ECMO system is imperative to providing safe, effective extracorporeallife support.
