Acid/Base Disturbances #2

Question 1

What happens if we have a high CO2 and a low HCO3-?

Answer 1

Mixed acidosis (respiratory and metabolic acidosis)

Question 2

What occurs when diarreah?

Answer 2

Poop out bicarb= internal bicarb decreases = decrease in pH

Question 3

Hyperventilation

Answer 3

Causes respiratory alkalosis

Question 4

What occurs during hypoventillation?

Answer 4

You are not getting rid of the CO2 you are producing.

So CO2 goes up= pH increase= respiratory acidosis

Question 5

What occurs during hyperventillation?

Answer 5

You are getting rid of more CO2 than you can produce.

= blood pH will increase = respiratory alkalosis

Question 6

Hypoventillation results in respiratory ______

Answer 6

Acidosis

Question 7

Hyperventillation results in respiratory _______

Answer 7

Alkalosis.

Question 8

What has the worst prognosis?

Answer 8

Metabolic alkalosis

Question 9

In real like, will there only be a change in one of the pHs of PCO2 and HCO3-?

Answer 9

No. Both will change due to mass action.

Question 10

Thus, in a more realistic situation, what will occur during respiratory alkalosis?

Answer 10

CO2 levels will decrease.

Bicarb will also decrease, but only slightly.
