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 396
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 395
72 year old man with history of COPD presented with shortness of breath. His chest auscultation revealed bilateral wheezes.
His arterial blood gas on 40% O2 showed the following:
PH = 7.29
PCO2 = 60 mmHg
Lab case 394 Interpretation
Answers:
Question 1:
PH = 7.475, that is mild alkalaemia.
pCO2 = 24 mmHg. So, we have respiratory alkalosis.
Lab case 394
14-year-old girl, COVID day 2, presented with delirium. Her venous blood gases showed the following:
Ph = 7.475
pCO2 = 24 mmHg
Lab case 393 interepretation
PH = 7.28, that is moderate acidaemia.
PCO2 = 73 mmHg. This means we have respiratory acidosis.

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.
