* 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)
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.

Baseline Dyspnea Index (BDI)
Baseline Functional Capability, Dyspnea as measured with the Baseline Dyspnea Index (BDI)
Time frame: At baseline once upon entry into the study
Transition Dyspnea Index (TDI)
Improvement in Functional Capability, Dyspnea as measured with the Transition Dyspnea Index (TDI)
Time frame: Every two weeks after baseline up to three months
Chronic Respiratory Disease Questionnaire (CRQ)
Improvement in Quality of Life as measured with the Chronic Respiratory Disease Questionnaire
Time frame: At baseline upon study entry and change from baseline every two weeks up to three months
Oxygen Saturation
Assess pulse oximetry saturation at baseline on setting to maintain oxygen saturation equal to or greater than 90% at rest and with activity every two weeks to determine improvement or equivalence
Time frame: At baseline upon study entry and change from baseline every two weeks up to three months
Six Minute Walk Distance
Assess distance covered in meters at baseline over 6 minutes and every two weeks up to three months to determine improvement in functional capability
Time frame: At baseline upon study entry and change from baseline every two weeks up to three months
Portable Oxygen Source Utilization
Reduction in Portable Oxygen Source Use from baseline on enrollment with assessments of use each day throughout study period to determine if there are utilization reductions resulting in cost savings during study period.
Time frame: 6 Months
Healthcare Utilization
Unscheduled Hospital, Emergency Room or Physician Office Visits, as measured from baseline 6 months prior to study entry and during study period to identify utilization changes if any.
Time frame: 6 Months
