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
