1

Metabolic Acidosis

PCO2 = 1.5 (HCO3) + 8

2

Metabolic Alkalosis

PCO2 = 40-.07(HCO3-24)

3

Respiratory Acidosis Acute

HCO3 = 24 + [(PCO2-40)/10]

4

Respiratory Acidosis Chronic

HCO3 = 24 + 4 [(PCO2-40)/10]

5

Respiratory Alkalosis Acute

HCO3 = 24-2[(40-PCO2)/10]

6

Respiratory Alkalosis Chronic

HCO3 = 24-5[(40-PCO2)/10]

7

Respiratory Acidosis Acute Rule of Thumb

HCO3 will increase 1 meq/L for each 10 mmHg PCO2 is above 40

8

Respiratory Acidosis Chronic Rule of Thumb

HCO3 will increase 4 meq/L for every 10 mmHg PCO2 is above 40

9

Respiratory Alkalosis Acute Rule of Thumb

HCO3 will decrease 2 meq/l for each 10 mmHg that PCO2 is below 40

10

Respiratory Alkalosis Chronic Rule of Thumb

HCO3 will decrease 5 meq/l for each 10 mmHg that PCO2 is below 40
