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 Intervention Phase
Acute Cardiogenic Pulmonary Edema Other: standard therapy (ST) Device: CPAP Device: BIPAP Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: CPAP Versus BiPAP in Acute Cardiogenic Pulmonary Edema: Experience With 129 Patients

Study Completion Date: November 2007
Primary Completion Date: November 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: CPAP + ST
Continuous positive airway pressure (CPAP) and Standard medical therapy (ST)
Device: CPAP
Non-invasive mechanical ventilation (CPAP)
Other Names:
  • Continuous postive air way pressure
  • noninvasive positive support ventilation (NPSV)
Active Comparator: BiPAP + ST
Bilevel positive airway pressure (BiPAP) and standard medical therapy (ST)
Device: BIPAP
Non-invasive mechanical ventilation (BIPAP)
Other Name: Bilevel Positive Airway Pressure ventilation
Active Comparator: ST
Standard Medical therapy (ST)
Other: standard therapy (ST)
standard medical therapy
Other Name: Medical treatment of acute cardiogenic pulmonary oedema

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.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. CPE confirmed radiologically and/or clinically
  2. Severe acute respiratory failure (partial arterial oxygen (PaO2)/Fraction of inspired oxygen (FIO2) less than 250)
  3. Dyspnea of sudden onset with respiratory
  4. Systolic blood pressure < 180 mmHg

Exclusion Criteria:

  1. Immediate need for endotracheal intubation:

    • Severe sensorial impairment

    • Ventricular arrhythmias,
    • Life-threatening hypoxia (SpO2 [oxygen saturation as indicated by pulse oximetry] less than 80% with oxygen)
    • Acute myocardial infarction necessitating thrombolysis
    • Cardiac or respiratory arrest
  2. Severe chronic renal failure
  3. Pneumothorax.
  4. Contraindication of non invasive ventilation (NIV)
