mEq/L

• pH: 7.35-7.45

• PaCO₂: 35-45 mmHg

• HCO₃⁻: 22-26 mEq/L

• Sodium: 135-145 mEq/L

• Chloride: 98-107 mEq/L

• Anion Gap: 8-16 mEq/L

1. pH: Acidemia (<7.35), Normal (7.35-7.45), Alkalemia (>7.45)

2. Primary disorder: Metabolic vs Respiratory

3. Compensation: Appropriate, Over, or Under-compensated

4. Anion gap: Normal (8-16) or High (>16) gap acidosis

Arterial blood gas interpretation is essential for evaluating acid-base status, ventilation, and oxygenation in critically ill patients.

Always correlate ABG results with clinical presentation, electrolytes, and patient history for accurate diagnosis and management.
