Aerial blood gas analysis of a patient reveals - pH 7.2, HCO3 36 mmol/L pCO2 70 mmHg. The abnormality is: (A) Respiratory acidosis with metabolic alkalosis, (B) Respiratory acidosis, (C) Respiratory alkalosis with metabolic acidosis, (D) Respiratory acidosis with metabolic acidosis
Answer is A. Answer- A. Respiratory acidosis with metabolic alkalosisIn this patientpH - DecreasedHCO3 - IncreasedPCO2 - IncreasedPCO2 is increased which indicates respiratory acidosisHCO3- is increased which indicates metabolic alkalosisThus this is a case of mixed disorder, where respiratory acidosis and metabolic alkalosis exist together.
