STATS/ACID BASE

Question 1

Expected Compensation for Metabolic Acidosis

Answer 1

PC02 = 1.5(HC03) + 8+/- 2 (Winters Formula)
PCO2 > Expected = Respiratory Acidosis
PCO2 < Expected = Respiratory Alkalosis

Question 2

Expected Compensation for Metabolic Alkalosis

Answer 2

For each increase 1.0 in HC03, PC02 increase by 0.7

Question 3

Expected Compensation

1. Acute Respiratory Acidosis
2. Acute Respiratory Alkalosis

Answer 3

(1,2) The bicarb should increase by 1 above 24 for every 10mmg of above 40 mm hg.

The bicarb should decrease by 2 for every 10mmg decrease below 40

HC03 < Expected there is complicating metabolic acidosis
HC03 > Expected there is complication metabolic alkalosis

Question 4

Expected Compensation

1. Chronic Respiratory Acidosis
2. Chronic Respiratory Alkalosis

Answer 4

(4,5) the HC03 increases by 4 for every 10 mm hg increase above 40 in PC02

The HC03 decreases by 5 for every 10 mmm decrease in PC02 from 40

HC03 < Expected there is complicating metabolic acidosis
HC03 > Expected there is complication metabolic alkalosis
