pH= 7.30, pCO2= 38, HCO3 = 18, Diagnosis is?
Since pH is less, and HCO3 is less, it implies metabolic acidosis Now for compensation pCO2 = HCO3+ 15 = 18 + 15 = 33 The value predicted is not matching with given pCO2 of 38 mmHg. It implies compensation is not there and it is a mixed disorder. Conclusion metabolic acidosis with respiratory acidosis.
