Does Continuous Positive Airway Pressure by Face Mask Improve Patients With Acute Cardiogenic Pulmonary Edema Due to Left Ventricular Diastolic Dysfunction?

In-Hospital Treatment of Obstructive Sleep Apnea During Decompensation of Heart Failure

“…34 Several studies demonstrated that noninvasive ventilation was safe in this setting, and resulted in improved gas exchange, increased LVEF, and reduced left ventricular filling pressure in patients with ADHF. 34,35,36 To our knowledge, this is the first study to evaluate the use of PAP designed only to maintain the patency of the upper airway during sleep and not as a form of ventilation in the setting of ADHF. We excluded patients with significant hypoxia or hemodynamic instability.…”

Acute effects of positive end-expiratory pressure on left ventricle diastolic function in healthy subjects

“…The only study that evaluated TTE parameters in ACPE patients treated with CPAP during the acute event was designed by Bendjelid and co-workers [24]. However, these authors studied few patients, and did not properly focus their evaluation on diastolic function by collecting parameters like Vp and DT.…”

Mechanical Ventilation in Patients with Hypoxemia due to Refractory Heart Failure

“…Two recent meta-analyses assessed additional benefits of noninvasive ventilation (NIV) and suggested that the NIV should be strongly considered as a first-line treatment in patients with acute CPE (16,17 cardiac output and blood pressure, patients with cardiac dysfunction and elevated pulmonary capillary wedge pressure may benefit from the decrease in preload and afterload (18). Earlier studies demonstrated that the continuous positive airway pressure (CPAP) was beneficial for hypoxemia in patients with CPE by increasing LVEF and decreasing LVEDV and the pressure support plus PEEP induced similar pathophysiological benefits (19,20 …”
