I don't understand why this is metabolic alkalosis, partially compensated.

The pH is 7.47 which is increased, therefore it is alkalosis but the CO2 and HCO3- are both elevated...which makes me believe it would be combined? Does it have anything to do with the fact that the HCO3- is farther out of range than the CO2 and that's why it is metabolic alkalosis?

Metabolic alkalosis, partially compensated

If HCO3- caused the acidosis or the alkalosis, it is METABOLIC if CO2 caused the acidosis or alkalosis, it is RESPIRATORY if CO2 and HCO3- caused the imbalanced, it is COMBINED To determine compensation: Uncompensated= abnormal pH and change in one blood parameter Partially compensated= all 3 values of pH, HCO3-, CO2 are abnormal Fully compensated= pH is normal, both HCO3- and CO2 are abnormal Corrected= all parameters are normal Normal ranges: pH is 7.35-7.45 HCO3- is 22-26 CO2 is 35-45
