ABGs

Question 1

What do hypoventilation and hyperventilation cause?

Answer 1

Hypoventilation

Leads to hypercapnia, low oxygen and causes respiratory acidosis

Hyperventilation
Hypocapnia as CO2 is breathed off, high oxygen, causes alkalosis

Question 2

What can hyperthermia cause?

Answer 2

Shift of oxygen dissociation curve to the right

Question 3

Answer 3

Acute uncompensated respiratory acidosis

Question 4

Answer 4

Acute uncompensated respiratory alkalosis

Question 5

Answer 5

Acute uncompensated metabolic alkalosis

Question 6

Answer 6

Chronic partially compensated respiratory acidosis

Question 7

Answer 7

Acute uncompensated metabolic acidosis

Question 8

Answer 8

Chronic partially compensated metabolic acidosis

Question 9

Answer 9

Acute uncompensated respiratory acidosis

Type 2 respiratory failure

Question 10

Answer 10

Chronic partially compensated respiratory alkalosis

Type 1 respiratory failure

Question 11

Answer 11

Chronic partially compensated metabolic acidosis

Question 12

Answer 12

Chronic mixed respiratory and metabolic acidosis

HCO3- very low, indicating acidosis as does the lowered O2 and raised CO2

(Base excess was also very low keeping with metabolic acidosis)

Question 13

Answer 13

Uncompensated metabolic acidosis

Question 14

Answer 14

Partially compensated respiratory alkalosis

(as the HCO3 has dropped suggesting trying to decrease pH)

Question 15

Work out the anion gap here

Answer 15

Na- (HCO3+ Cl)
140-(16+100)=24

24>16 therefore high anion gap

High anion gap suggests metabolic acidosis

Question 16

Answer 16

Uncompensated metabolic acidosis

Question 17

Answer 17

Uncompensated metabolic acidosis
