Lab case 392 interpretation
Answers:
PH = 7.10, that is severe acidaemia.
HCO3 = 11 mmol/L, this means we have metabolic acidosis.
Next, we need to calculate the anion gap and the compensation.

Lab case 390 interepretation
Question 1:
PH = 6.88, that is severe acidaemia
HCO3= 5.3 mmol/L. So, we have metabolic acidosis.
Next step is to calculate the anion gap to know which type of metabolic acidosis and we need to calculate the respiratory compensation.
