ABG Review
Blood Gas Result
pH = 7.3
pCO2= 51
HCO3= 24
pO2= 50
O2 Sat= 80%
ROME
R = Respiratory

O = Opposite

M = Metabolic

E = Equal
pHCO3
Normal: 22-26
Acidotic: <22 (Low Value)
Alkalotic: >26 (High Value)
3. Label your pHCO3 Acidotic (Low), Alkalotic (High), or normal
Normal: 7.35 - 7.45
(Absolute: 7.4)
Acidotic: < 7.35 (Low Value)
Alkalotic: >7.45 (High Value)
pH
1. Label your pH Acidotic (Low) or Alkalotic (High)
pCO2
Normal: 35-45
Alkalotic: <35 (Low Value)
Acidotic: >45 (High Value)
2. Label your pCO2 Acidotic (High), Alkalotic (Low), or normal
pH= 7.27
Acidotic
Low
pCO2= 53
Acidotic
High
pHCO3= 24
Normal
Respiratory Acidosis
Just a few more steps...
pO2
Normal= 80-100
Hypoxia= <80

O2 Sat
Normal= 95%-100%
Hypoxia= <95%
Putting it all together...
What does all this mean??
4. Match either the pCO2 or the pHCO3 to the pH
5. Apply *ROME
R=Respiratory, O=Opposite, M=Metabolic, E=Equal
7. Are the pO2 or the O2 Sat out of range?
Compensation
6. The metabolic & respiratory systems are the only two that work to maintain pH
Therefore, ABG values are either:
1. Fully Compensated

2. Partially Compensated

3. Uncompensated
(pH normal & pCO2 et. pHCO3 out of range)
(When 2 values out of range [pH, pCO2, or pHCO3])
(All three values out of range)
pH=7.3
*pH was low
pCO2=51
*pCO2 was high
pHCO3=24
*pHCO3 was normal
Uncompensated Respiratory Acidosis
pO2=50
*pO2 was low (hypoxic)
O2 Sat=80%
*O2 Sat was low (hypoxic)
with Hypoxia
Uncompensated Respiratory Acidosis with Hypoxia
Practice
1.
pH= 7.29
pCO2= 31
pHCO3= 16
pO2= 70
O2 Sat= 92%
2.
pH= 7.36
pCO2= 30
pHCO3= 14
pO2= 82
O2 Sat= 95%
