-Summary
This study is to evaluate the efficacy of a new therapy (Automatic Expiratory Positive Airway Pressure with intelligent Volume Assured Pressure Support (AutoEPAP iVAPS)) designed to treat respiratory insufficiency, respiratory failure and/or nocturnal hypoventilation with upper airway obstruction. The study will be performed in two phases: In a sleep unit and in the home environment. The new therapy will be compared against two existing ventilator therapies: "Spontaneous Timed (ST) mode" and "Intelligent Volume Assured Pressure Support (iVAPS)".

+Detailed description
Phase I: AutoEPAP iVAPS will be compared against two existing ventilator therapies: "Spontaneous Timed (ST) mode" and "Intelligent Volume Assured Pressure Support (Fixed EPAP iVAPS)" in current NIV users with respiratory insufficiency and /or respiratory failure due to Chronic Obstructive Pulmonary Disease (COPD),Obesity Hypoventilation Syndrome (OHS) or Neuromuscular Disease (NMD). Patients will spend a total of 3 nights in the sleep laboratory in the three modes described above. The apnoea-hypopnoea index will be the primary outcome measure.
Phase II: AutoEPAP iVAPS will be compared to ST mode over a period of 7 nights in the patients' home. The mean EPAP setting of each device will be the primary outcome measure.
+Arms and interventions
| Arm | Type | Interventions | Description |
|---|
| Standard ST Mode | Active comparator | Device: Juno | Participants underwent the first PSG study (Titration Night 1) on ST Mode ( prior to going on AutoEPAP iVAPS or Fixed EPAP iVAPS) whilst receiving their standard NIV therapy through the clinical trial device "Juno". During this mode the participant's current NIV settings were reviewed and re-titrated to deliver optimal therapy. |
| AutoEPAP iVAPS | Experimental | Device: Juno | Participants underwent a PSG study on the AutoEPAP iVAPS mode on either Night 2 or Night 3 according to their computer generated randomisation.
Participants were randomised (1:1) according to a computer-generated randomised list (Microsoft Excel 2010) to receive 'AutoEPAP iVAPS' or 'FixedEPAP iVAPS' therapy mode first. |
| Fixed EPAP iVAPS | Active comparator | Device: Juno | Participants underwent a PSG study on the Fixed EPAP iVAPS mode on either Night 2 or Night 3 according to their computer generated randomisation.
Participants were randomised (1:1) according to a computer-generated randomised list (Microsoft Excel 2010) to receive 'AutoEPAP iVAPS' or 'FixedEPAP iVAPS' therapy mode first. |

+Outcome measures
Primary outcomes

- Mean Oxygen Saturation [1 night]: Mean oxygen saturation recorded in the total sleep time
- Time Spent Below 90% Oxygen Saturation [1 night]: Time in minutes that the oxygen saturation was below 90%
- Mean Transcutaneous Carbon Dioxide (PtcCo2) [1 night]: Transcutaneous Carbon Dioxide measurement (TcCO2)
- Sleep Duration [1 Night]: Time spent asleep
- Sleep Efficacy [1 Night]: Sleep time divided by total time available for sleep
- Sleep Latency-Wake After Sleep Onset Time [1 Night]: Time awake in minutes after initial sleep onset
- Total Sleep Time Spent in Each Sleep Stage [1 Night]: Percentage of total sleep time spent in each sleep stage (ie. N1, N2, N3 and REM)
- Number of Respiratory Event Related Arousals/ Hour [1 Night]: Total number of respiratory event related arousals/hr over the entire sleep period
- Number of Spontaneous Arousals/Hour [1 Night]: Number of spontaneous arousals/hr occurring over the entire total sleep time
