pCO2 = 12.6 mmHg
18-year-old girl presented after a large quantity of weight losing pills. Her blood gases showed the following:
PH = 7.659
pCO2 = 12.6 mmHg
This patient’s blood test showed high K level with low Mg and Ca levels.
Deranged electrolytes levels usually happen due to one of five reasons:
63 years old man presented with vertigo. His bloods showed the following:
Na = 136 mmol/L
K = 6.3 mmol/L
PH = 7.55, that is moderate alkalaemia.
PCO2 = 30 mmHg (Less than 40) so we have respiratory alkalosis.
28-year-old female doctor developed severe migraine episode after finishing night shifts. She vomited multiple times. Her venous blood gases showed the following:
PH = 7.55

18 year old woman recently returned from overseas, she presented with fever and was diagnosed with ITP with platelets count of 54. Her Liver Functions Tests shows the following:
Bilirubin = 26 umol/L
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.
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
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.
