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
* Determine the affect of the Portable Oxygen Concentrator (POC) on improvements in:

1. Exercise capability, dyspnea and quality of life as primary endpoints
2. Utilize:

1. Baseline Dyspnea Index (BDI)
2. Transitional Dyspnea Index (TDI)
3. Chronic Respiratory Disease Questionnaire (CRQ)
4. Six minute walk test (6MWT)
5. Epworth Sleepiness Scale (ESS)
* The secondary endpoints will be:

1. Rate of exacerbations, sleep quality
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 the affect of the Portable Oxygen Concentrator on improvements in exercise capability, dyspnea and quality of life as primary endpoints, utilizing the Baseline Dyspnea Index (BDI), Transitional Dyspnea Index (TDI), the Chronic Respiratory Disease Questionnaire (CRQ) and six minute walk test (6MWT). The secondary endpoints will be rate of exacerbations, sleep quality (reported as number of hours sleep improvement; utilize Epworth Sleepiness Scale \[ESS\]), and health care utilization (emergency room encounters, hospital admissions).

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 4th leading cause of death in the U.S.
* Breathing difficulty is the major reason patients seek medical attention
* COPD patients requiring hospitalization were 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 will be provided a lightweight portable oxygen concentrator to:

1. support increased activity
2. improve quality of life
3. increase functional capacity

No interventions assigned to this group
