Findings

# Lab case 396 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 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

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.
