Answers:
PH = 7.56, that is moderate alkalaemia
HCO3 = 38.4 mmol/L, so we have metabolic alkalosis.
Next, we will calculate the compensation. For metabolic alkalosis we use the following equation:

An alcoholic man presented to the emergency department after suffering from a seizure. His venous blood gases showed the following:
PH = 7.56
pCO2 = 42 mmHg
Answers:
PH = 7.30, that is mild acidaemia.
pCO2 = 65 mmHg. So, we have respiratory acidosis.
Next, we need to look at the compensation. Compensation for respiratory acidosis is different between acute and chronic cases.
