Q

uncompensated respiratory acidosis:
pH:

HCO3: slightly high

20
Q

compensated respiratory acidosis:
pH:
PCO2:
HCO3:

A

pH: low, moving toward baseline

HCO3: very high due to compensatory production of acidic urine

21
Q

uncompensated metabolic acidosis
pH:
PCO2:
HCO3:

A

pH: low
PCO2: normal
HCO3: low

22
Q

compensated metabolic acidosis
pH:
PCO2:
HCO3:

A

pH: slightly low, moving toward baseline
PCO2: decreased due to compensatory hyperventilation
HCO3: very low; decreased more due to decrease PCO2

23

pH: high
PCO2: low
HCO3: slightly low

24
Q

compensated respiratory alkalosis:
pH:
PCO2:
HCO3:

A

pH: slightly high, moving toward baseline
PCO2: low
HCO3: very low due to compensatory alkalotic urine production

25

PCO2:
HCO3:

A

pH: high
PCO2: normal
HCO3: increased

26
Q

compensated metabolic alkalosis
pH:
PCO2:
HCO3:

A

pH: slightly high, moving toward baseline
PCO2: high due to compensatory hypoventilation
