<prompt> pH 7.30, pCO2 38, HCO3 18, Diagnosis is?Metabolic acidosis with compensatory respiratory alkalosisRespiratory acidosis with compensatory metabolic alkalosisRespiratory alkalosis with compensatory metabolic acidosisMetabolic acidosis with respiratory acidosis  <response>: 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.
