8 years old asthmatic boy, presented with croupy cough and wheezy chest. His blood gases showed the following:
PH = 7.299
pCO2 = 52 mmHg
Category Archives: Lab Cases
Lab case 363 interpretation
Question 1:
PH = 7.52, that is moderate alkalaemia
pCO2 = 34, so we have respiratory alkalosis.
Next we calculate the compensation.
Lab case 363
50 year old man presented to the emergency department with vomiting. He is an excessive THC smoker.
His blood gases showed the following:
PH = 7.52
Lab case 362 interpretation
Question 1:
PH = 7.299 that is mild acidaemia
pCO2 = 80 mmHg, So we have metabolic acidosis. Next we need to calculate the compensation.
Lab case 362
77 year old lady referred by GP for shortness of breath on exertion. Her venous blood gases showed the following:
PH = 7.299
pCO2 = 80 mmHg
Lab case 361 interpretation
Question 1:
For synovial fluid analysis. WBC level more than 50,000 (especially if more than 80,000) is suggestive of septic arthritis.
Lab case 361
60 year old man with painful knee effusion. Synovial fluids analysis showed the following:
Lab case 360 Interpretation
Question 1:
PH = 7.19, that is severe acidaemia.
HCO3 = 14 mmol/L, So we have metabolic acidosis. Next, we need to calculate respiratory compensation and anion gap.
Lab case 360
78 year old diabetic man, presented to ED feeling unwell. His venous blood gases showed the following:
PH = 7.19
pCO2 = 39 mmHg
Lab case 359 interpretation
Question 1:
PH = 7.38, that is within the normal range, toward the acidotic side.
pCO2 is 62 mmHg, that is high. Usually this number is associated with respiratory acidosis.
