PRIMARY outcome

Timeframe: 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.

Population: Per protocol analysis

Measure
NIOV - Room Air
n=15 Participants
Subjects exercise using the NIOV device powered by compressed air (room air, 21% O2). NIOV - Room Air: Noninvasive ventilation with device powered by compressed room air.
NIOV - Oxygen
n=15 Participants
Subjects exercise using the NIOV device powered by compressed medical oxygen (100% O2). NIOV - Oxygen: Noninvasive ventilation with device powered by compressed medical (100%) oxygen.
Nasal Cannula Oxygen
n=15 Participants
Subjects exercise using a standard nasal cannula using medical oxygen (100% O2). Nasal Cannula Oxygen: Supplemental oxygen delivered using a standard nasal cannula connected to 100% medical oxygen.
No Treatment
n=15 Participants
Control arm. Subjects exercise without using supplemental oxygen or NIOV.

Population: Per Protocol

Mean differences between NIOV - oxygen, NIOV - Room Air, Nasal Cannula Oxygen, and no treatment (control) at isotime. Borg Dyspnea Score ranges in values from 0 to 10. The lower score represent better outcome. 0 = No breathlessness at all, representing better outcome 10 = Maximum breathlessness, representing worse outcome
