80 year old man presented with shortness of breath. This patient had history of CHF and COPD. His venous blood gases showed the following
- PH = 7.409
- pCO2 = 54 mmHg
Lab case 454 interpretation
PH = 7.39, that is within the normal range.
pCO2 = 30 mmHg, that is slightly low. This patient might have respiratory alkalosis.
Next, we should look at the compensation for respiratory acidosis. (This patient is 2 years old. The condition will be acute).

Lab case 454
2-year-old boy brought to ED by ambulance as category 1 for severe croup. His blood gases showed the following.
PH = 7.39
Lab case 453 interpretation
PH = 6.782, that is severe acidaemia.
HCO3 = 2.5 mmol/L, that is extremely low. So we have metabolic acidosis.
Next we need to calculate the compensation and find out what type of metabolic acidosis this patient has.
