acid-base workup TLDR

代謝性的 → 呼吸代償 = f(HCO3) → 同向跟上

  • PaCO2 = (1.5 × HCO3) + 8 ± 2 (Winters’ formula)
    • e.g. HCO3 = 12, PaCO2 = 26
  • PaCO2 = 0.7 × (HCO3-24) + 40 ± 2 or HCO3 + 15
    • e.g. HCO3 = 36, PaCO2 = 50

漲五成+8 v.s. 打七折+40


呼吸性的 → 代謝代償 → 同向跟上 HCO3 = f(pCO2/20mmHg)

  • Recid pCO2 超高
    • +2(Acute)
    • +7(Chronic)
  • Reka pCO2 超低
    • -4(Acute)
    • -8(Chronic)

我去!西八!


  • AG (12±2) normal = Na- Cl - BiCar
  • DG = Na- Cl - 12
    • AGMA + MetAlk : 30 : AGMA : 18 : AGMA + NAGMA
    • (Na-Cl) AGMA + MetAlk : 42 : AGMA : 30 : AGMA + NAGMA
    • if 🧂sodium = 140:
      • 110: AGMA + NAGMA (阿哥馬加那個馬)
      • 98: AGMA + MetAlk (阿哥馬加鹼)
