HYDROGEN ION
HOMEOSTASIS
CHM60304 CLINICAL CHEMISTRY

2. STEPS TO ABG INTERPRETATION

3. EXAMPLE - CASE 1
• ABG Results:
pH : 7.30 (7.35 - 7.45)
pCO2: 55 (35 - 45)
HCO3: 26 (22 – 26)
• Interpretation:
pH : 7.30 (Acid)
pCO2: 55 (Acid) = Lungs
HCO3: 26 (Normal) = Kidneys
• Interpretation:
Respiratory acidosis

4. STEPS TO ABG INTERPRETATION IN COMPENSATION

5. EXAMPLE - CASE 2
• ABG Results:
pH : 7.38 (7.35 - 7.45)
pCO2: 56 (35 - 45)
HCO3: 35 (22 – 26)
• Interpretation:
pH : 7.38 (NORMAL)
pCO2: 55 (Acid) = Lungs
HCO3: 35 (Alk) = Kidneys
• Use pH 7.40
7.38 = Acid
• Interpretation:
Respiratory acidosis - compensated
