Here's how I go about doing these problems -

1) Look at the ph ... if its low then Acidosis, if its high then Alkalosis.

2) Look at the pCo2 ... if its high then respiratory acidosis, if its low then respiratory alkalosis.

For metabolic acidosis the pH would be low and your bicarbonate (HCO3-) would be low as well but as a compensation you would hyperventilate to decrease pCO2. For metabolic alkalosis the pH would be high and your bicarbonate would be high as well and as a compensation you would hypoventialte to increase pCO2.

Just remember, look at pH first and decided between Acidosis and Alkalosis. Next look at pCO2.

In respiratory acidosis the compensation would be bicarbonate retention and in resp alkalosis the compensation would be bicarbonate excretion.


Does this help ?
