A Study to Evaluate Improvement in the Quality of Life and Health and Economic Outcomes of Patients Diagnosed With Chronic Obstructive Pulmonary Disease (COPD)
- Evaluate subjects in an prospective observational study
- Subjects will be administered scientifically validated questionnaires
- Evaluate Quality Improvement and Oxygen Utilization Improvements.
1. Functional capability, dyspnea, oxygen saturation as primary endpoints
1. Baseline Dyspnea Index (BDI)
2. Transitional Dyspnea Index (TDI)
3. Chronic Respiratory Disease Questionnaire (CRQ)
4. Six minute walk distance (6MWD)
5. Oxygen saturation using pulse oximeter
- The secondary endpoints:
1. Portable oxygen source utilization
2. Health care utilization (emergency room encounters, hospital admissions)
- Subjects will be administered scientifically validated questionnaires
- Evaluate Quality Improvement and Oxygen Utilization Improvements.

Evaluate subjects in an prospective observational study in which subjects will be screened
and administered scientifically validated questionnaires at study entry and during the
observation period at specified intervals to determine Quality Improvements through using the
Breath Responsive Variable Bolus Oxygen Conserving Device with a Portable/Ambulatory Oxygen
Source on improvements in functional capability, dyspnea, oxygen saturation, quality of life
as primary endpoints, and portable oxygen source utilization, health care utilization as
secondary endpoints.
