In which of the following condition does an ABG analysis show: pH 7.2,| PaC02, |HC03:

The ABG analysis given in the question points to a mixed acid-base disorder, Respiratory acidosis-Metabolic acidosis. In this condition there is a high or normal anion-gap metabolic acidosis; prevailing PaCO2 above predicted value. This is seen in conditions like severe pnuemonia, pulmonary edema. The given Blood Gas analysis profile cannot be explained by either metabolic or respiratory alkalosis alone, even with or without compensation.
