Artery blood gas analysis動脈血氣體分析:
1. Artery blood gas分析需要的項目
2. Artery blood gas判讀步驟
(1) 預測疾病
(2) pH value
(3) primary disorder
(4) compensation
(5) Anion gap
3. Metabolic acidosis
(1) Anion gap
(2) Δ/Δ delta-delta(delta ratio)
4. Some mixed disorders
5. Anion Gap metabolic acidosis鑑別診斷

判讀時要注意primary disorder,也就是先看pH值
