Brief Summary
Pilot study in 15 stable male subjects with severe-to-very severe Chronic Obstructive Pulmonary Disease (COPD) to evaluate the effects of short term use of the Breathe Technologies noninvasive open ventilation (NIOV) system on respiratory mechanics during constant work rate exercise in subjects with severe COPD.

Outcome Measures
Primary Outcomes (1)
Exercise Duration for Constant Work Rate Exercise Tests Under 4 Test Conditions
Mean differences between NIOV - oxygen, NIOV - Room Air, Nasal Cannula Oxygen, and no treatment (control).
Study days 1,2,3, and 4; Day 1 for no treatment; day 2 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 3 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 4 for NIOV - oxygen and Nasal Cannula Oxygen.
Secondary Outcomes (2)
SpO2 During Constant Workrate Exercise at Isotime
Outcome was measured in each of the Study day 1,2, 3 and 4. Study days 1,2,3, and 4; Day 1 for no treatment; day 2 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 3 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 4 for NIOV - oxyg
Borg Dyspnea Score During Constant Workrate Exercise at Isotime
Outcome was measured in each Study day 1,2,3 and 4. Study days 1,2,3, and 4; Day 1 for no treatment; day 2 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 3 for no treatment and NIOV - Room Air and NIOV - oxygen; Day 4 for NIOV - oxygen and N
Study Arms (4)
NIOV - Room air
EXPERIMENTALSubjects exercise using the NIOV device powered by compressed air (room air, 21% O2).
NIOV - Oxygen
EXPERIMENTALSubjects exercise using the NIOV device powered by compressed medical oxygen (100% O2).
Nasal Cannula Oxygen
ACTIVE COMPARATORSubjects exercise using a standard nasal cannula using medical oxygen (100% O2).
No treatment
NO INTERVENTIONControl arm. Subjects exercise without using supplemental oxygen or NIOV.
Interventions
Noninvasive ventilation with device powered by compressed room air.
Noninvasive ventilation with device powered by compressed medical (100%) oxygen.
Supplemental oxygen delivered using a standard nasal cannula connected to 100% medical oxygen.
Eligibility Criteria
You may qualify if:
- Adult males, ≥ 40 years of age
- Diagnosis of severe COPD (GOLD stage III or IV) defined as having a FEV1 \< 50% of predicted and an FEV1/FVC ratio \< 70% of predicted
- Ventilatory limitation to exercise, documented by a VE/MVV \> 0.85
- SpO2 between 80% and 88% during incremental exercise testing on room air
- Willingness and ability (after training) to exercise on a cycle ergometer
- Willingness and ability to perform all other study related procedures and tasks
- Ability to be properly fitted with the Breathe nasal mask
- Ability to tolerate and be appropriately titrated on the Breathe ventilator (See Appendix E)
- Ability to be properly fitted with an exercise mask
- Fluency in written and spoken English
- Provision of written informed consent
You may not qualify if:
- History of acute exacerbation of COPD within 30 days of screening
- History of serious epistaxis within 14 days of screening
- Requirement of \> 5 LPM nasal O2 to maintain an SpO2 \> 90% while at rest
- History of pneumothorax secondary to lung bullae
- History of intolerance to supplemental oxygen
- Musculoskeletal or other non-pulmonary impairment that limits exercise tolerance
- Inability to achieve an optimal CWR level (4-7 minutes) during Study Visit 1R
- Current participation in another interventional study or participation within 14 days of screening
- Presence of any condition or abnormality that in the opinion of the Principal Investigator may compromise the subject's safety or the quality of the study data
