NUABG (Arterial Blood Gas) looks complicated… but it’s actually a simple story of balance inside your body.
Think of it like this👇
🫁 Lungs control CO₂ (acid)
🧠 Kidneys control HCO₃⁻ (base)
⚖️ Body tries to keep pH normal (7.35–7.45)
Now the trick👇
👉 Step 1: Check pH
Low pH = Acidosis
High pH = Alkalosis
👉 Step 2: Look at CO₂ & HCO₃⁻
CO₂ ↑ = Respiratory Acidosis
CO₂ ↓ = Respiratory Alkalosis
HCO₃⁻ ↓ = Metabolic Acidosis
HCO₃⁻ ↑ = Metabolic Alkalosis
👉 Step 3: See compensation
Body always tries to fix imbalance (lungs or kidneys adjust)
💡 Easy hack to remember:
“ROME”
Respiratory = Opposite
Metabolic = Equal
✨ In short:
ABG tells you if the problem is from lungs or metabolism and how the body is trying to fix it.
