39.2.0.2 ⭐ 高 yield

39.2.0.2.1 Differential
Onset + Setting Likely
Sudden + pleuritic PE / Pneumothorax
Sudden + chest pain + diaphoresis MI
Progressive + orthopnea/PND HF
Wheeze + smoking COPD / asthma
Fever + cough + crackles Pneumonia
Stridor + drooling Epiglottitis
Kussmaul respiration Metabolic acidosis (DKA)
39.2.0.2.2 Wells Score (PE)
  • DVT signs 3
  • PE > other dx 3
  • HR > 100 1.5
  • 制動 / surgery 4 wk 1.5
  • Past PE/DVT 1.5
  • Hemoptysis 1
  • Cancer 1

≥ 4 → CTA< 4 → D-dimer

39.2.0.2.3 NIV (BiPAP)
  • AECOPD with hypercapnia
  • Acute cardiogenic pulmonary edema
  • Hypoxemic respiratory failure (cautious)
  • 犁忌意識差、埪環䞍穩、嘔吐、面郚創傷
39.2.0.2.4 COPD O2 Risk
  • 絊 high O2 → blunting hypoxic drive → CO2 retention
  • Target SpO2 88-92%
  • Venturi mask titrate
39.2.0.2.5 HF Acute Mx (LMNOP)
  • Lasix
  • Morphine郚分
  • Nitrates
  • O2
  • Position upright
    • BiPAP
39.2.0.2.6 Asthma Severe
  • Nebulizer albuterol + ipratropium
  • Steroid (prednisone PO or methylpred IV)
  • MgSO4 2 g IV
  • Heliox
  • Avoid sedation 過量
  • Intubate if 嚎重 acidosis / 意識差

39.2.0.3 🎯 自我檢枬

  1. COPD O2 target? → 88-92%

  3. Tension PTX 處眮? → Needle decompression
  4. HF NIV 適應? → Acute pulmonary edema
  5. Asthma MgSO4? → 2 g IV
  6. BNP < 100? → HF unlikely
  7. Status asthmaticus 譊瀺? → 沉默 chest, paradoxical, exhaustion
  8. Acute pulmonary edema 急救? → LMNOP + BiPAP
