55 year old male patient who is a know case of chronic kidney disease present to emergency with vomiting and Is diagnosed with uremic acidosis. His ABG analysis report is
pH= 7.42
pCO2= 40
HCO3= 25
Na+= 140 mmol/L
K+= 3 mmol/L
Cl-= 95 mmol/L
PH is higher, but CO2 and HCO3 look normal. So look at Anion gap = 20 .
But difference in HCO3 = 0  so is a case of High Anion Gap metabolic acidosis + metabolic alkalosis.
Respiratory acidosis
Respiratory Alkalosis
High Anion Gap metabolic acidosis + metabolic alkalosis
High Anion Gap metabolic acidosis + Respiratory Alkalosis
