| | ECMO Circuit (Site not responding. Last check: 2007-11-06) |
 | | In Veno-arterial ECMO (the kind Theresa has), the second cannula allows blood which has passed round the circuit and is now high in oxygen and low in carbon dioxide to re-enter the baby into a main artery and circulate around the body. |
 | | The profusionist and ECMO nurse check the clotting time (ACT) of the blood in the circuit every one to two hours and adjust the heparin infusion to keep this at the best level to minimize the risk of bleeding. |
 | | Aside from the ECMO ciruit, there are several other machines recording her vital signs, the ventilator, medicine pumps, etc. For the most part, unless we are actively watching the monitors, we watch Theresa, and now I don't even notice all the machines, tubing, and wires, and only see my little girl. |
