Primary Outcome Measures:
  • Device Tidal Volume [ Time Frame: Periodically over six hours x 5 days ]
    Evaluate the mean test volume for three activity levels. Subjects completed five consecutive, 6-hour clinic days in which the NIOV system was worn continuously while at rest, during activities of daily living (ADLs).


Secondary Outcome Measures:
  • Device Preference [ Time Frame: At conclusion of subject's participation (up to two weeks) ]

    5-point Likert Scale completed at the end or the 5-day study period

    - Preference Scale: 5 = Max preference (Prefer to use the test device), 1 = Min preference (Do not prefer to use the test device)


  • Safety and Device-related Adverse Events [ Time Frame: Continuous from Study Day 2 through Study Day 6 ]
    Any adverse events reported during he study period.


Enrollment: 22
Study Start Date: August 2011
Study Completion Date: October 2011
Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Noninvasive Open Ventilation System
Portable noninvasive open ventilator & nasal interface.
Device: Noninvasive Open Ventilation System
Noninvasive ventilation system

Detailed Description:

The primary objective of the study was to evaluate the Breathe Technologies Ventilator System with regard to subject acceptability, comfort, and effect on exercise and activities of daily living tolerance.

Primary Hypothesis:

  1. When using the Breathe Technologies Ventilation System during simulated activities of daily living (ADL), Subjects with moderate-to-severe COPD will be comfortable and report acceptability.

    Secondary Hypotheses:

  2. When using the Breathe Technologies Ventilation System during simulated ADLs, Subjects with moderate-to-severe COPD will experience tolerable dyspnea as measured using the Borg Dyspnea Score (BDS) and a visual analog Comfort Scale (VACS).
  3. Subjects will prefer using the Breathe Technologies Ventilation System over standard oxygen therapy during exertion and during ADLs after using the ventilator therapy for five days.

  • Report having a smoking history of ≥ 10 pack-years.
  • Provide written informed consent to participate in the study.

Exclusion Criteria:

Subject must NOT meet any of the following criteria, or they will be excluded from study participation:

  • Be a current tobacco smoker
  • Have a history of pneumothorax in last 2 years.
  • Have a history of severe, giant bullae.
  • Have a history of unstable angina
  • Reports the onset of cardiac arrhythmia(s) within the past 7 days.
