Interpret the following data.
What is your diagnosis?
|A||Uncompensated metabolic acidosis|
|B||Uncompensated. Respiratory acidosis.|
|C||Compensated Respiratory acidosis|
|D||Compensated metabolic acidosis|
Compensated metabolic acidosis
In this question the PH is 7.40 (i.e. normal) so acid base disturbance has been compensated so option A and B are ruled out. Here PCO2 is 20 (i.e. respiratory alkalosis) so option C is ruled out.
As PH is 7.4 (compensated) and HCO3 is 8. Hence Option D is the answer.
