Study information
Scientific title
The effectiveness of ambulatory oxygen versus room air during pulmonary rehabilitation in patients who are hypoxaemic on exertion and respond to supplemental oxygen at baseline
Acronym
Study hypothesis
The aims of this prospective randomised controlled trial is to determine whether ambulatory oxygen during pulmonary rehabilitation provides additional benefit, compared with room air, for patients hypoxaemic only on exertion and who respond to supplemental oxygen at baseline. Additionally, to determine whether the degree of acute response to ambulatory oxygen predicted any additional benefit.
Ethics approval
Surrey Ethics Committee approved on the 7th August 2007 (ref: 07/H1109/89)

Primary outcome measures
Exercise tolerance measured using the Endurance Shuttle Walk Test pre- and post-pulmonary rehabilitation
Secondary outcome measures
1. Quality of life measured using the Self-Report Chronic Respiratory Questionnaire
2. Anxiety and depression measured using the Hospital Anxiety and Depression Scale
3. Function measured using the Surrey Information on Function Tool
All are questionnaires completed pre- and post-pulmonary rehabilitation.
