“…Another important aspect is the albumin and phosphate anion charges included in the expression of total weak anions (ATot). [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ] This physicochemical approach highlights the possibility that a decrease or an increase in these variables may cause metabolic alkalosis or acidosis, respectively. A number of studies showed that ATot as a whole was not modified throughout the session or the CRRT because the increment in albumin charge after the session was compensated by the decrease in the phosphate charge.…”
