Capnometry-Assisted Breathing Training for COPD
In Brief
A Phase 2 clinical trial evaluating Capnometry-Assisted Training for COPD to Slow the Breath (CATCH) and Pulmonary Rehabilitation (PR) for Chronic Obstructive Pulmonary Disease. Completed, enrolled 31 participants across 1 site.
Detailed 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.

Timeline
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).
