Question 1:
PH = 7.28, that is mild acidaemia
HCO3 = 17 mmol/L. So we have metabolic acidosis.
The main finding is prolonged QT interval.
Use Bazett formula to calculate QTc. In this case 516 msec
QTc is prolonged if:
Question 1:
PH = 7.409, that is with in normal range
pCO2 = 54 mmHG, that is suggestive of respiratory acidosis.
HCO3 = 33.3, that is suggestive of metabolic alkalosis.
35-year-old lady with palpitations. Her ECG as below.
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
Answers:
PH = 7.547 that is moderate alkalaemia.
pCO2 = 24 mmHg, so we have respiratory alkalosis.
84 year old man with history of asthma and COPD presented with acute shortness of breath. His venous blood gases showed the following:
PH = 7.547
pCO2 = 24 mmHg
Answers:
Question 1:
PH = 7.58, that is severe alkalaemia.
pCO2 = 20 mmHg, so we have respiratory alkalosis. Next we need to calculate the compensation. From the story, the condition is most likely acute.
