Management of Pulmonary Edema

Initial Assessment and Stabilization

The European Society of Cardiology recommends positioning the patient in a semi-seated or upright position to improve ventilation and decrease venous return 1, 3
Administer oxygen therapy immediately to maintain SpO₂ >90% in hypoxemic patients, avoiding routine oxygen use in non-hypoxemic patients, as suggested by the European Heart Journal 2, 3
Establish continuous monitoring of ECG, blood pressure, heart rate, and oxygen saturation for at least the first 24 hours, according to the European Heart Journal 4, 3
Obtain intravenous access for medication administration, as recommended by the European Society of Cardiology 1, 3

Apply Continuous Positive Airway Pressure (CPAP) or Non-Invasive Positive Pressure Ventilation (NIPPV) early in patients with respiratory distress, as recommended by the American Thoracic Society 1, 2
CPAP and NIPPV significantly reduce the need for endotracheal intubation and may decrease mortality, according to the American Thoracic Society 1, 2
Consider intubation and mechanical ventilation if there is persistent hypoxemia, hypercapnia with acidosis, deteriorating mental status, or hemodynamic instability despite interventions, as suggested by the European Society of Cardiology 1, 3

The American College of Cardiology recommends nitroglycerin as the first-line therapy for acute cardiogenic pulmonary edema, starting with sublingual nitroglycerin 0.4-0.6 mg, repeated every 5-10 minutes as needed 2, 3
For intravenous nitroglycerin, start at 0.3-0.5 μg/kg/min and titrate to achieve optimal vasodilation while maintaining systolic blood pressure >85 mmHg, as recommended by the American College of Cardiology 2, 3
Administer intravenous loop diuretics (e.g., furosemide) shortly after diagnosis for rapid symptomatic relief, according to the European Heart Journal 2, 3

Identify and treat the underlying cause, such as acute coronary syndrome, valvular disease, or hypertensive crisis, as recommended by the American Heart Association 2, 3
For acute coronary syndrome, consider urgent myocardial reperfusion therapy (cardiac catheterization or thrombolytic therapy), according to the American College of Cardiology 2, 3

Consider intraaortic balloon counterpulsation for patients with severe refractory pulmonary edema, particularly if urgent cardiac catheterization is needed, as suggested by the European Society of Cardiology 2, 3
Ventricular assist devices or other forms of mechanical circulatory support may be considered in selected patients, according to the European Heart Journal 4, 3

Evaluate response to treatment through clinical parameters (respiratory rate, use of accessory muscles), as recommended by the American Thoracic Society 1, 3
Monitor fluid intake and output, renal function, and electrolytes, according to the European Society of Cardiology 2, 3

Avoid excessive rapid reduction of blood pressure as it may compromise organ perfusion, as warned by the European Society of Cardiology 3
Do not apply CPAP in patients with hypotension (systolic blood pressure <90 mmHg), according to the American Thoracic Society 1
Avoid morphine in patients with respiratory depression or severe acidosis, as cautioned by the European Society of Cardiology 3
