<prompt> An ABG analysis shows : pH 7.2, raised pCO2, decreased HCO3;diagnosis is :Respiratory acidosisCompensated metabolic acidosisRespiratory and metabolic acidosisRespiratory alkalosis  <response>: Answer is C Respiratory and metabolic acidosis lhe acid base disorder is therefore both respiratory and metabolic acidosis. There is acidosis pH 7.35. Raised PCO2 acidosis indicates that change in CO2 is in keeping with change in p1-1. The respiratory component is therefore primary. Decreased HCO3 acidosis indicates that change in HCO3 is also primary . The acid base disorder is therefore both respiratory and metabolic acidosis.
