Hemodialyzer (H) vs. artificial lung (AL). An in vitro study for Extracorporeal CO2 remov AL (CO2R)

Adult respiratory distress syndrom[6] could be treated . in Intensive Care Unit using Extracorporeal (EC) CO₂R techniques. In order to obtain the lowest blood flow rate ECCO2 appears to be the earliest and easiest procedure. ECCO2 can be achieved either by using AL or H. CO2R with the AL device concerns the "dry" form (dissolved CO2) whereas the H device involves the "wet" form of CO2 (bicarbonates). The work under study compares one AL (DIDECO D702) with one H (HOSPAL H10-10) device under different in vitro conditions. Four series of experiments were achieved : I. AL D702 without acidification II.AL D702 with inlet HC1 acidification III.H H10-10 without dialyzate alkalinization IV.H H10-10 with NaOH dialyzate alkalinization.
