Acid Base and Blood Gas Analysis
1. pH - What’s the primary disturbance?
2. pCO2 - What’s the pCO2?
3. HCO3 - What’s the bicarb?
Respiratory Acidosis - Airflow obstruction
 • COPD, asthma, ↓ Drive, Medications, Central, ↑ CO2 production
Respiratory alkalosis
 drive
• Hypoxemia
• Pain/anxiety
• Hepatic enceph
• Pregnancy
• Salicylates
Metabolic Alkalosis - “BLVD PLACE”
   B - Bartter's
   L – Laxative
   V – Vomiting
   D - Diarrhea/diuretics
   P - Post-hypercapnea
   L - Licorice
   A - Alkali ingestion
   C - Contraction alkalosis
   E - Endocrine (Conn’s or Cushing’s)
Metabolic Acidosis
  - non anion gap metabolic acidosis
  - anion gap metabolic acidosis
