A
Change in Na (Na infusate - Na serum)/(total body water +1)
TBW 0.5 x kg women 0.6 x kg men
Volume needed
2
Q
ABG
A
H = 24 (PCO2/HCO3) Metabolic Acidosis PCO2 1.2 Metabolic Alkalosis PCO2 0.6 Respiratory Acidosis HCO3 0.4 Respiratory Alkalosis HCO3 0.6
Calculate AG
Check Delta-Delta +dHCO3 - dAG
+ non-AG MA
- Metabolic alkalosis
