Goals of MECMO Circuit

Decrease surface area

Decrease prime volume

Decrease blood product requirements

Minimize bleeding and thrombosis

Allow for safe transport of circuit
Circuit Revisions

Change in oxygenator

Decreased length and diameter of tubing (1/4 inch to
3/16 inch)

Elimination of components without a biocompatible
surface coating

Conclusions

In patients less than 10kg there was less blood loss
and decreased blood product requirements within
first 72 hours of surgery.

No difference in thrombosis or circuit change

Console can be mounted to patient bed or pole
allowing for easier transport.
