Lab case 440
80-year-old lady presented with confusion. Her Venous blood gases showed the following:
PH = 7.396
pCO2 = 52 mmHg
Lab case 439 Interpretation
Question 1:
PH = 7.30 that is mild acidaemia.
HCO3 = 16 mmol/L (>24) so we have metabolic acidosis.
Next, we need to calculate the anion gap and the compensation (using Winter’s formula)

Lab case 439
61-year-old man presented to ED with hypoglycemia that was difficult to correct with oral and IV dextrose. His venous blood gases showed the following.
PH = 7.30
PCO2 = 33 mmol/L
Lab case 438 Interpretation
Answers:
PH = 7.39, that is within normal range/
pCO2 = 48 mmHg, that is slightly elevated (Can be considered normal for venous blood)
HCO3 = 29 mmol/L. That is high (Normal value is 24 mmol/L), SO, we have metabolic alkalosis.
