- pH: 7.35 - 7.45
- PaO2: 80 - 100 mmHg
- SaO2: 95% - 100%
- PaCO2: 35 - 45 mmHg
- HCO3: 22 - 26 mEq/L
- CO2= Respiratory and supports Acid-Base balance
- HCO3= Metabolic and supports Acid-Base balance
ROME METHOD
- R: Respiratory, pH value: Opposite, PCO2: Abnormal, HCO3: Normal
- O: Opposite, pH value: Opposite, PCO2: Abnormal, HCO3: Normal
- M: Metabolic, pH value: Same, PCO2: Normal, HCO3: Abnormal
- E: Equal, pH value: Same, PCO2: Normal, HCO3: Abnormal
- Uncompensated or not compensated= Primary disturbance present, no compensatory response yet; pH is abnormal.
- Partial Compensation= Body is attempting to correct the imbalance; pH is still abnormal but moving toward normal.
- Full or Compensated= Body has successfully corrected the pH back to normal range despite ongoing primary disturbance.
Respiratory Acidosis: pH < 7.35, PaCO2 > 45, HCO3 Normal (Uncompensated) or > 26 (Compensated)
Respiratory Alkalosis: pH > 7.45, PaCO2 < 35, HCO3 Normal (Uncompensated) or < 22 (Compensated)
Metabolic Acidosis: pH < 7.35, PaCO2 Normal (Uncompensated) or < 35 (Compensated), HCO3 < 22
Metabolic Alkalosis: pH > 7.45, PaCO2 Normal (Uncompensated) or > 45 (Compensated), HCO3 > 26
