Summary

This pilot study is part of a phased approach to refine, optimize, and test the feasibility of CALM Breathing. Preliminary participant feedback from the Capnography-Assisted Respiratory Therapy (CART) study was applied to adapt and design CALM Breathing (including its dose, schedule, delivery, and home program). This pilot builds on initial lessons learned and identifies intervention areas still needing greater development to assure the success of a future large trial, targeting a subpopulation at risk, that is, those with COPD and anxiety sensitivity.

BEHAVIORAL

CALM Breathing

CALM Breathing is a mind-body breathing therapy that links CO2 changes to dyspnea and anxiety symptoms and targets breathing efficiency and self-efficacy in COPD. CALM Breathing: Individual interoception- based breathing therapy with capnography (non- exercise training) Home Program: Monitored home- based breathing exercises; RR biofeedback; goal setting; exercise logging. Coaching: Motivational interviewing. Personnel: PT, EP, occupational therapist, or nurse. Frequency: 1-hour sessions, twice per week for 4 weeks. Exercises: • 10 core breathing exercises with ETCO2 biofeedback in recovery postures at rest and with body movement (gentle stretches and brief low-moderate intensity physical activity). • Breathing biofeedback (ETCO2, RR, airflow pattern). Education: Education on anxiety; COPD Patient Guide.

BEHAVIORAL

Traditional outpatient PR

After referral to Columbia's outpatient pulmonary rehabilitation (PR) program, participants randomized to the Wait-List control group will be put on a PR wait list (usual care). In Phase II, all participants will receive PR of 1-hour sessions, twice per week for 10 weeks. Traditional outpatient PR: Group exercise training (ET) combined with pursed lips breathing (PLB) training; 1:2 therapist to patient ratio. Home Program: Unmonitored walking exercise 1-2 days/week; no biofeedback monitoring. Coaching: Traditional monitoring and verbal cueing. Personnel: PT or EP. Frequency: 1-hour sessions, twice per week for 10 weeks. Exercises: • ET of muscles of ambulation with exercise equipment, such as on a treadmill or cycle ergometer (30-min), plus 15-min strengthening and posture exercises; O2 supplementation as needed. No breathing biofeedback. • PLB instruction only during exercise training. Education: Verbal and written information.
