A 26-year-old man is admitted to the ICU because of bacterial sepsis. Labs are as follows:
Arterial blood gases (room air) PH 7.2 PCO2 32 mm Hg PO2 96 mm Hg
Serum HCO3- 12 mEq/L
Which of the following is the normal initial compensatory response to this pH?
A) Decreased excretion of HCO3- B) Decreased respiratory rate C) Increased excretion of HCO3- D) Increased respiratory rate

D?
cuz i think this is metabolic acidosis so the comensation will be resp. alkalosis which can be done by blowing off more CO2 (hyperventilation)

the above acid base picture shows combined respiratory and metabolic acidosis coz the normal pCO2 compensation in metabolic acidosis is given by winters formula=1.5 (HCO3)+8=1.5(12)+8=26,the given pCO2 is 32 mmHg,anyways the answer is
