Brief Summary:
Cardiogenic pulmonary edema (CPE) is a common medical emergency and noninvasive ventilation (NIV) in addition to conventional medical treatment might be beneficial for patients with CPE.

Condition or disease Intervention/treatment Phase
Acute Cardiogenic Pulmonary Edema Other: standard therapy (ST) Device: CPAP Device: BIPAP Phase 4

Detailed Description:
To evaluate the effect of adding continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP) to standard medical therapy (ST) on intensive care unit (ICU) stay, hospital stay, mortality, need for endotracheal intubation, partial arterial O2 tension (PaO2), intrapulmonary shunt, alveolar-arterial (A-a) oxygen gradient, and cardiac output in patients admitted to the respiratory intensive care unit (ICU) or cardiac care unit (CCU) with acute CPE with gas exchange abnormalities and to evaluate the impact of heart failure type on the outcome of different therapeutic schedules.
