Metabolic acidosis
PaCO2 = (1.5 x HCO3-) + 8
Or
PaCO2 will ↓ 1.25 mmHg per mmol/L ↓ in [HCO3-]
Or
PaCO2 = [HCO3-] + 15
Metabolic alkalosis
PaCO2 will ↑ 0.75 mmHg per mmol/L ↑ in [HCO3-]
Or
PaCO2 will ↑ 6 mmHg per 10 mmol/L ↑ in [HCO3-]
Or
PaCO2 = [HCO3-] + 15
Respiratory alkalosis
 
Acute
[HCO3-] will ↓2 mmol/L per 10 mmHg ↓ in PaCO2
Chronic
[HCO3-] will ↓ 4 mmol/L per 10 mmHg ↓ in PaCO2
Respiratory acidosis
 
Acute
[HCO3-] will ↑ 1 mmol/L per 10 mmHg ↑ in PaCO2
