Simon TI - Acceptability of capnography-assisted respiratory therapy: a new mind–body intervention for COPD AID - 10.1183/23120541.00256-2021 DP - 2021 Oct 01 TA - ERJ Open Research PG - 00256-2021 VI - 7 IP - 4 4099 - http://openres.ersjournals.com/content/7/4/00256-2021.short 4100 - http://openres.ersjournals.com/content/7/4/00256-2021.full SO - erjor2021 Oct 01; 7 AB - Dyspnoea self-management is often suboptimal for patients with COPD. Many patients with COPD experience chronic dyspnoea as distressing and disabling, especially during physical activities. Breathing therapy is a behavioural intervention that targets reducing the distress and impact of dyspnoea on exertion in daily living.Using a qualitative design, we conducted interviews with 14 patients after they participated in a novel mind–body breathing therapy intervention adjunct, capnography-assisted respiratory therapy (CART), combined with outpatient pulmonary rehabilitation. Comprehensive CART consisted of patient-centred biofeedback, tailored breathing exercises, a home exercise programme and motivational interviewing counselling. We assessed participants’ perceptions and reported experiences to gauge the acceptability of CART and refine CART based on feedback. Constant comparative analysis was used to identify commonalities and themes.We identified three main themes relating to the acceptability and reported benefits of CART: (1) self-regulating breathing; (2) impact on health; and (3) patient satisfaction. Our findings were used to refine and optimise CART (i.e. its intensity, timing and format) for COPD.By addressing dysfunctional breathing behaviours and dysregulated interoception, CART offers a promising new paradigm for relieving dyspnoea and related anxiety in patients with COPD.Capnography-assisted respiratory therapy (CART) is a new adjunctive mind–body therapy. Patients with COPD find CART to be acceptable and to complement pulmonary rehabilitation. https://bit.ly/3iP4glN
