APPARATUS FOR EXTRACORPOREAL TREATMENT OF BLOOD AND METHOD FOR DETERMINING WATER LOSSES IN A MEMBRANE GAS EXCHANGER OF AN APPARATUS FOR EXTRACORPOREAL TREATMENT OF BLOOD
Application US20260091165A1 Kind: A1 Apr 02, 2026
Inventors
Dominique Pouchoulin
Abstract
A method for determining water losses in a membrane gas exchanger of an apparatus for extracorporeal treatment of blood, comprises:
obtaining a sweep gas flow rate (Qgas) in a gas side of a membrane gas exchanger (19); obtaining a water saturation content (Csaturationout) at a gas outlet (19d) of the membrane gas exchanger (19); calculating the water losses (Qeccor) as a function at least of the sweep gas flow rate (Qgas) and the water saturation content (Csaturationout).
