Chronic Obstructive Pulmonary Disease
Conditions
Brief summary
Capnometry-Assisted Breathing Training for COPD (CATCH) is a behavioral intervention that aims to promote optimal, self-regulated, mindful breathing. A portable capnometer is used in-session to provide continuous visual feedback of Respiratory Rate (RR), End-Tidal Carbon Dioxide Tension (ETCO2), and breathing pattern. The tailored CATCH intervention will emphasize a slow, quiet, regular, nasal breathing pattern, as well as pursed lips breathing (PLB). CATCH is once weekly for 6 weeks, for a total of 6 sessions; each session is approximately 60 minutes long. The principal investigator will implement the CATCH intervention. The principal investigator will implement the CATCH intervention. Patients will use the Address Stress app on a smart phone or computer tablet as part of their home breathing exercises.
Interventions
Tailored intervention emphasizing slow, quiet, regular nasal breathing pattern.
Patients in both treatment groups will participate in a 10 week (16-20 sessions) comprehensive PR program. The control group will receive the 10-Week PR program with traditional breathing training sessions (without biofeedback). The program comprises 2 or 3 exercise training sessions per week by physical therapists (each 1 hour duration).

| Difference in Mean Dyspnea Management Questionnaire Computer Adaptive Test (DMQ-CAT) Anxiety Score Between Pre and Post Intervention | 2 weeks pre intervention and 4 weeks post intervention | The DMQ-CAT Dyspnea Anxiety is a 14 item scale; each item is scored off a 7 point likert scale for a total range of 0 to 98 where higher scores correlate with higher anxiety |

| Difference in Mean 6MWT Distance Between Pre and Post Intervention | Week 0 and Week 10 | The six-minute walk test (6MWT) measures the distance an individual is able to walk over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes. |
| Mean Difference in Resting Respiratory Rate Between Pre and Post Intervention | 0 weeks and 10 weeks | — |
| Difference in Mean Score on St George's Respiratory Questionnaire (SGRQ) Between Pre and Post Intervention | Week 0 and Week 10 | Disease-specific instrument designed to measure impact on overall health, daily life, and perceived well-being in patients with obstructive airways disease. Scores range from 0 to 100, with higher scores indicating more limitations. |
| Difference in Mean PROMIS Fatigue Score Between Pre and Post Intervention | 0 weeks and 10 weeks | Patient-Reported Outcomes Measurement Information System (PROMIS) Fatigue 7a questionnaire. Raw scores range from 7-35, with higher scores indicating higher levels of fatigue. |
