Brief Summary

Patients with chronic respiratory failure such as those associated with Chronic Obstructive Pulmonary Disease (COPD), Obesity Hypoventilation Syndrome (OHS), Obstructive Sleep Apnea (OSA) or Neuromuscular Disease (NMD) are increasingly managed with domiciliary non-invasive positive pressure ventilation (NIPPV). The aim of this study is to now compare the Automatic Expiratory Positive Airway Pressure (AutoEPAP) algorithm with a fixed manual EPAP in iVAPS mode on an Astral mixed mode ventilator. It is proposed that the automatic settings of AutoEPAP will be as effective at managing respiratory failure and upper airway obstruction (UAO) as manual EPAP on the Astral device. Specifically demonstrating that the AutoEPAP function is as effective at treating UAO as manual EPAP.

Outcome Measures

Primary Outcomes (1)

  • Oxygen Desaturation Index 4% (ODI4%)

    Mean paired difference AutoEPAP-manual EPAP: Comparison of Oxygen Desaturation Index 4% (ODI4%) values between groups by using mean ODI4% (#events/hour). A cross-over analysis was generated to investigate the influence of a possible period effect on the primary endpoint, paired change in ODI4% between Auto and manual EPAP

    Overnight, up to 8 hrs on nights 1 and 2

Secondary Outcomes (4)

  • Sleep Efficiency (%)

    Overnight, up to 8 hrs on nights 1 and 2

  • Apnea Hypopnea Index (AHI)

    Overnight, up 8 hrs on night 1 and 2

  • Nadir Arterial Oxygen Saturation (SpO2)

    Overnight, up 8 hrs on night 1 and 2

  • Arterial Carbon Dioxide (PCO2)

    Overnight, up 8 hrs on night 1 and 2

Study Arms (2)
