For this pilot study patients who meet the conventional criteria for pulmonary rehabilitation at their clinical appointments will be recruited and scheduled to return for the study. After completing the informed consent, patients will be taught how to don and doff the pulse oximeter, the source of the heart rate and oxygen signals. Patients will participate in a demonstration on how to perform the intervention. Recruitment will continue until five patients have completed the pilot in a clinic setting. If necessary, the prototype will be modified and testing resumed. Once the prototype system has met the criteria for success in the clinic, five of patients will be asked to use the prototype at the clinic and to take it home for a week and perform the intervention at least five times.
