Background
- Cardiogenic vs Non-Cardiogenic (ARDS/Altitude/Neurogenic)
- Mechanism of Cardiogenic
- Failing heart > pulm edema > stress response > incr afterload
- Incr afterload > incr pulm edema
- Failing heart > pulm edema > stress response > incr afterload
- Pts often intravascularly depleted; avoid diuretics!
Diagnosis
- Crackles
- Respiratory distres
Treatment
- CPAP/BiPAP with PEEP 6-8; titrate up to PEEP of 10-12
- Nitroglycerin
- Dosing Options
- Sublingual 0.4 mg q5min
- Intravenous: 0.1mcg/kg/min - 5mcg/kg/min
- Dosing Options
Generally start IV Nitroglycerin 50mcg/min and titrate rapidly (150mcg/min or higher)to symptom relief
