Acute Pulmonary Edema Management

Initial Assessment and Intervention

The American College of Cardiology recommends positioning the patient in a semi-seated position to improve ventilation 2
The European Society of Cardiology suggests administering oxygen therapy immediately to hypoxemic patients to achieve arterial oxygen saturation ≥95% (≥90% in COPD patients) 3, 4
The American College of Cardiology recommends establishing intravenous access for medication administration 2
Continuous monitoring of ECG, blood pressure, heart rate, and oxygen saturation is essential, as recommended by the American College of Cardiology 1, 2

The European Society of Cardiology recommends non-invasive ventilation (NIV) with positive end-expiratory pressure (PEEP) to improve clinical parameters and reduce the need for intubation 3, 4
The European Society of Cardiology suggests applying CPAP with initial PEEP of 5-7.5 cmH2O, titrated up to 10 cmH2O based on clinical response; FiO2 should be set at 0.40 3, 5
Contraindications to NIV include inability to cooperate (unconsciousness, severe cognitive impairment), immediate need for endotracheal intubation due to progressive life-threatening hypoxia, as stated by the European Society of Cardiology 3, 6

The American College of Cardiology recommends administering sublingual nitroglycerin (0.4-0.6 mg every 5-10 minutes) as initial therapy 8, 7
The American College of Cardiology suggests initiating intravenous nitroglycerin (starting dose 0.3-0.5 μg/kg/min) if systolic blood pressure is acceptable (≥95-100 mmHg) 8, 7
The American College of Cardiology recommends administering intravenous furosemide (20-80 mg) shortly after diagnosis of acute pulmonary edema is established 8, 7
The European Society of Cardiology suggests using diuretics cautiously in patients with hypotension (SBP <90 mmHg), severe hyponatremia, or acidosis, as they are unlikely to respond 3, 9

The American College of Cardiology recommends evaluating response to treatment through clinical parameters (respiratory rate, use of accessory muscles) 2
The American College of Cardiology suggests monitoring oxygen saturation, arterial blood gases, renal function, and electrolytes 2
Consider placement of a pulmonary artery balloon catheter if the patient's clinical course is deteriorating, recovery is not proceeding as expected, high-dose vasodilators are required, inotropes are needed, or there is uncertainty about the diagnosis, as recommended by the American College of Cardiology 8, 1

The American College of Cardiology recommends considering urgent myocardial reperfusion therapy (cardiac catheterization, coronary angiography, appropriate interventional procedure, or thrombolytic therapy) for patients with acute myocardial infarction 7, 5
The American College of Cardiology suggests considering intraaortic balloon counterpulsation and urgent surgical intervention for severe refractory pulmonary edema with a correctable lesion (e.g., papillary muscle rupture with acute mitral regurgitation) 8
Avoid intraaortic balloon counterpulsation in patients with significant aortic valvular insufficiency or aortic dissection, as stated by the American College of Cardiology 8, 2
