Validation of Continuous Transcutaneous Carbon Dioxide Monitoring in VA-ECMO Patients

Carbon dioxide in patients on veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is eliminated via respirator as well as via the oxygenator's membrane of the ECMO machine. Consequently, monitoring of end-tidal carbon dioxide tensions is limited, which can result in marked swings towards non-physiological values. Hyper- and hypocapnia, however, can have detrimental …
