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

Primary disorder

problem

pH

HCO3

PaCO2

Metabolic alkalosis

loss of H+ / gain of HCO3

↑↑

Metabolic acidosis

gain of H+ / loss of HCO3

↓↓

Respiratory alkalosis

hyperventilation

↓↓

Respiratory acidosis

hypoventilation

↑↑
