- 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 via lungs
- HCO3= Metabolic and supports Acid-Base balance via kidneys

ROME METHOD:
- R: Respiratory — pH opposite to PaCO2
- O: Opposite — pH and PaCO2 move in opposite directions
- M: Metabolic — pH same as HCO3
- E: Equal — pH and HCO3 move in same direction

Definitions:
- Uncompensated or not compensated= Primary disorder present, no compensatory response yet; pH abnormal, only one value (PaCO2 or HCO3) abnormal
- Partial Compensation= Body is beginning to compensate; pH still abnormal, both PaCO2 and HCO3 are abnormal but moving toward correction
- Full or Compensated= pH is normal despite abnormal PaCO2 and HCO3; compensation has restored pH to normal range

Acid-Base Disorders Table:
- 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
