The facial x-rays are from an adult with right cheek swelling, bruising & cough. Patient had sustained punch injury to their face earlier. What can be seen? Continue reading
70 year old man presented with reduced level of consciousness.
His venous blood gas showed the following:
PH = 7.31
PO2 = 62 mmHg (on 6L O2)
PH = 7.479, that is mild acidaemia.
HCO3 = 30 mmol/L (that is high). So, we have metabolic alkalosis.
Next we check the respiratory compensation for metabolic alkalosis. For That we use the following equation: Expected pCO2 = 0.7 x HCO3 + 20 (+/- 5).
Adult patient with sepsis. What can be seen? Continue reading
28 days old boy brought by his parents for multiple vomiting episodes. His venous gases showed the following:
PH = 7.479
pCO2 = 41 mmHg
pO2 = 34 mmHg
Question 1 answer
PH = 7.236, that is moderate acidaemia
HCO3 = 12.5 mmol/L. So we have metabolic acidosis.
Next we need to calculate the compensation and the the anion gap.
The chest x-ray is from an elderly patient with septic delirium. What can be noticed? Continue reading
