title: A new oxygenator change-out system and procedure.
abstract: Official reports relate that, in the US, one patient/month dies as a result of the emergency oxygenator change-out procedure, and the permanent injury of some patients is the result of current oxygenator change-out procedures or oxygenator failures, both in extracorporeal circulation (ECC) and extracorporeal membrane oxygenation (ECMO). The aim of this article is to evaluate a new system and procedure, dedicated to oxygenator change-out, represented by two three-way stopcocks inserted in the ECC line in use. A dedicated back-up oxygenator and circuit can be easily primed and connected to the dedicated connector on the stopcocks, then blood flow is diverted to the new oxygenator without interruption of the ECC. Tests performed showed that oxygenator change-out can be completed by perfusionists in 62.13 +/- 11.12 sec. Results obtained show that the new system and procedure allows fast, safe and reproducible oxygenator change-out without interruption of the ECC.
