| A | B |
|---|
| respiratory acidosis compensated | low pH, high total CO2 and dissolved CO2 |
| respiratory acidosis uncompensated | high pCO2 but normal CO2 content |
| metabolic alkalosis compensated | high pH, high bicarb and carbonic acid |
| metabolic alkalosis uncompensated | excess of bicarb with no change in pCO2 |
| respiratory alkalosis compensated | high pH, low pCO2 and bicarb |
| respiratory alkalosis uncompensated | deficit of dissolved CO2 but bicarb in normal range |
| metabolic acidosis compensated | low pH, total CO2 and pCO2 |
| metabolic acidosis uncompensated | deficit of bicarb, normal pCO2 |
| 20:1 | normal bicarb:carbonic acid ratio |
| 7.35-7.45 | pH reference range |
| 22-29 mmol/L | HCO3 reference range |
| 35-45 mmHg | pCO2 reference range |
