<prompt> An ABG analysis shows : pH 7.2, raised pCO2, decreased HCO3; diagnosis isRespiratory acidosisCompensated metabolic acidosisRespiratory and metabolic acidosisRespiratory alkalosis  <response>: pH 7.35 : acidosisraised PCO2 : respiratory component is primarydecreased HCO3- : this is also primarytherefore acid base disorder is both respiratory and metabolic acidosisRef: Harrisons 18e p364 Table 47-2
