Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

* 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)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Chronic Obstructive Pulmonary Disease

* More than 12 million adults are diagnosed with COPD
* COPD is the 3rd leading cause of death in the U.S.
* Breathing difficulty is the major reason patients seek medical attention
* COPD patients requiring hospitalization are associated with higher costs
* Oximetry is an important tool for assessing need for Long-Term Oxygen Therapy
* LTOT has been proven to improve survival and quality of life
* Patients provided with a breath responsive variable bolus oxygen conserving device:

1. support increased activity
2. improve quality of life
3. increase functional capability
4. reduce portable oxygen source utilization
5. maintain and/or improve oxygen saturation
