Activity Endurance Time [ Time Frame: Measured during single day study visit ]
Time in minutes of sustained activity while using test treatments
  • Dyspnea Score [ Time Frame: Periodically over four hours ]
    Borg Dyspnea Score (BDS)
  • Fatigue Score [ Time Frame: Periodically over four hours ]

  • Comfort Score [ Time Frame: Periodically over four hours ]
    Comfort Visual Analog Scale (VAS)

  • Arterial Oxygen Saturation [ Time Frame: Measured during activity testing in a single day study visit ]
    O2 saturation measured by pulse oximetry
  • Borg Dyspnea Score [ Time Frame: Measured during activity testing in a single day study visit ]

    Borg Dyspnea score is measured using a 11-point visual analog scale. The lower the score on the scale, the less breathlessness patient experiences. The score ranges from:

    0 = No breathlessness at all, representing better outcome 10 = Maximum, representing worse outcome

  • Heart rate [ Time Frame: Up to four hours each study visit ]
  • Respiratory rate [ Time Frame: Up to four hours each study visit ]
  • Oxygen saturation [ Time Frame: Up to four hours each study visit ]
    Pulse oximetry
  • Partial pressure of carbon dioxide measured transcutaneously (TcPCO2) [ Time Frame: Periodically over four hours ]
  • Actigraphy [ Time Frame: Up to four hours each study visit ]
    Actigraphy monitor
  • Quality of Life (QOL) [ Time Frame: Before intervention begins on the first study day (baseline); at the completion of the first study day; at the completion of study days 2-9. ]

In-home Evaluation of a Noninvasive Open Ventilation System in Patients With Severe Respiratory Insufficiency
In-home Evaluation of the Breathe Technologies Noninvasive Open Ventilation (NIOV™) System in Patients With Severe Respiratory Insufficiency
The Breathe NIOV™ System will reduce the work of breathing in subjects with chronic respiratory insufficiency who require long-term oxygen therapy (LTOT). The Breathe system will accomplish this by providing oxygen under pressure and augmenting the subject's spontaneous tidal volumes. The combination of efficient oxygen delivery, assisted ventilation, and a comfortable low-profile device, will result in a mean improvement in perceived well-being and ability to perform ADLs, as measured by patient-reported outcome (PRO) instruments.
This will be a prospective, open-label, crossover study in up to 12 stable subjects with chronic respiratory insufficiency who require LTOT. Each subject's standard oxygen therapy will be used as the control treatment and compared to the test ventilator system during selected activities of daily living. Subjects will participate in the study for up to 9 home visits, with Visits 1 and 2 each lasting for approximately 4 hours, and Visits 3-9 lasting approximately 1-2 hours each. Subjects may discontinue study participation at any time.
