Background

Pulmonary Edema Types

Pulmonary capillary wedge pressure <18 mmHg differentiates noncardiogenic from cardiogenic pulmonary edema[1]

Diagnosis

  • Crackles
  • Respiratory distress

Differential Diagnosis

Acute dyspnea

Emergent

Non-Emergent

Treatment

  1. CPAP/BiPAP with PEEP 6-8; titrate up to PEEP of 10-12
  2. Nitroglycerin
    1. Dosing Options
      1. Sublingual 0.4 mg q5min
      2. Nitropaste (better bioavailability than oral Nitroglycerin)
      3. Intravenous: 0.1mcg/kg/min - 5mcg/kg/min

Generally start IV Nitroglycerin 50mcg/min and titrate rapidly (150mcg/min or higher)to symptom relief

  • If NTG fails to reduce BP consider nitroprusside (reduces both preload and afterload) or ACE-inhibitiors (preload reducer)
  • After pt improves titrate down NTG as enaliprilat (0.625 - 1.25mg IV) or captopril are started
  • Morphine is no longer recommended do to increased morbidity
