Treatment with the blood-gas exchanger multiECCO2R for CO2 removal
Treatment of patients suffering from hypercapnia due to acute lung failure and acute kidney injury (AKI). Patients will be treated up to 72 hours with CVVHD/HDF with a standard multiFiltrate blood line kit (multiFiltrate or multiFiltrate Pro). In order to perform an ECCO2R procedure during CVVHD/HDF treatment, the blood-gas exchanger multiECCO2R is inserted in a specifically designed blood line kit downstream of the hemodialyzer.
