8 years old asthmatic boy, presented with croupy cough and wheezy chest. His blood gases showed the following:
PH = 7.299
pCO2 = 52 mmHg
8 years old asthmatic boy, presented with croupy cough and wheezy chest. His blood gases showed the following:
PH = 7.299
pCO2 = 52 mmHg
Question 1:
PH = 7.52, that is moderate alkalaemia
pCO2 = 34, so we have respiratory alkalosis.
Next we calculate the compensation.
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
Question 1:
PH = 7.299 that is mild acidaemia
pCO2 = 80 mmHg, So we have metabolic acidosis. Next we need to calculate the compensation.
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
Question 1:
For synovial fluid analysis. WBC level more than 50,000 (especially if more than 80,000) is suggestive of septic arthritis.
60 year old man with painful knee effusion. Synovial fluids analysis showed the following:
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.
78 year old diabetic man, presented to ED feeling unwell. His venous blood gases showed the following:
PH = 7.19
pCO2 = 39 mmHg
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.
