(13) C Breath Tests Are Feasible in Patients With Extracorporeal Membrane Oxygenation Devices.

abstract：:Tumor necrosis factor-alpha (TNF-alpha) release has been implicated in a sepsis-like syndrome following cardiopulmonary bypass (CPB). This also may be important in patients who have had a left ventricular assist device (LVAD) implanted. This report investigates the effect of reducing systemic blood flow on hemodynamic...
