Na = 136 mmol/L
K = 6.3 mmol/L
Lab case 373 interpretation
PH = 7.55, that is moderate alkalaemia.
PCO2 = 30 mmHg (Less than 40) so we have respiratory alkalosis.

Bilirubin = 26 umol/L
Lab case 371 interpretation
Question 1:
PH = 7.035, that is sever acidaemia
We have high pCO2 and low HCO3, this patient’s acidosis is most likely due to combination of metabolic and respiratory acidosis.
Lab case 371
53 years old type I diabetic lady was brought to the emergency department with tiredness, Blood gases were taken in ED. While awaiting the results of these gases the patient had a seizure. The blood gases (before the seizure) showed the following
PH = 7.035
pCO2 = 52 mmHg
Lab case 370 Interpretation
PH = 7.481, That is mild alkalaemia.
pCO2 = 21 mmHg, so we have metabolic alkalosis.
Next, we will calculate the compensation. It is not clear from the history if the respiratory alkalosis is acute or chronic.
Lab case 370
50 years old type 1 diabetic women presented with shortness of breath; her blood gases showed the following:
