Evaluation of Automatic Expiratory Positive Airway Pressure (Auto-EPAP) for Management of Upper Airway Obstruction During Non-Invasive Ventilation With Vivo 45 LS
To evaluate the safety and effectiveness of the Automatic Expiratory Positive Airway Pressure (Auto-EPAP) feature versus manual expiratory positive airway pressure (EPAP) in the Vivo 45 LS Ventilator.
• Subject has the ability to provide written informed consent.
• Subject is ≥ 18 years old.
• Subject has documented respiratory failure (e.g. sleep hypoventilation with historical transcutaneous carbon dioxide (PtCO2) increase ≥ 10mmHg) and/or daytime hypercapnia (\>45 mmHg).
• Subject is currently using non-invasive positive pressure ventilation (NIV) for 1 month.
• Subject has a previously documented apnea-hypopnea index (AHI) ≥ 5/hr.
• Subject's expiratory positive airway pressure (EPAP) settings were recently (≤ 12 months) reviewed.
