ABG Analysis

ABG Values:

pH = 7.35-7.24
HCO3 = 22-26 meq/L
PCO2 = 35-45 mmHg

Remember:

R - Respiratory
A- Alternate direction of arrows
M- Metabolic
S- Same direction of arrows

Examples:
1. pH= 7.5  (increased)
    HCO3 = 29 (increased)
    PCO2 = 50 (increased)

Result: Partially compensated metabolic acidosis

2.pH= 7.39 (normal)
   HCO3 = 29 (increased)
   PCO2 = 52 (increased)

Result: Fully compensated respiratory acidosis

3. pH = 7.31 (decreased)
   HCO3 = 29 (increased)
   PCO2 = 36 (normal)


Result: Uncompensated metabolic acidosis

  1. I think the top value for the pH is incorrect. Shouldn't it be 7.45 (not 7.24)?

  2. Yup. Normal is 7.35-7.45.
