“…Many authors have speculated on whether or not respiratory muscle function (RMF) is impaired in patients with DB. 48 Therefore, there seems to be insufficient evidence in the literature to support a positive or negative theoretical position regarding respiratory muscle dysfunction as a feature of DB.…”

Dysfunctional breathing: what do we know?

Dysfunctional breathing (DB) is a respiratory condition characterized by irregular breathing patterns that occur either in the absence of concurrent diseases or secondary to cardiopulmonary diseases. Although the primary symptom is often dyspnea or “air hunger”, DB is also associated with nonrespiratory symptoms such as dizziness and palpitations. DB has been identified across all ages. Its prevalence among adults in primary care in the United Kingdom is approximately 9.5%. In addition, among individuals with asthma, a positive diagnosis of DB is found in a third of women and a fifth of men. Although DB has been investigated for decades, it remains poorly understood because of a paucity of high-quality clinical trials and validated outcome measures specific to this population. Accordingly, DB is often underdiagnosed or misdiagnosed, given the similarity of its associated symptoms (dyspnea, tachycardia, and dizziness) to those of other common cardiopulmonary diseases such as COPD and asthma. The high rates of misdiagnosis of DB suggest that health care professionals do not fully understand this condition and may therefore fail to provide patients with an appropriate treatment. Given the multifarious, psychophysiological nature of DB, a holistic, multidimensional assessment would seem the most appropriate way to enhance understanding and diagnostic accuracy. The present narrative review was developed as a means of summarizing the available evidence about DB, as well as improving understanding of the condition by researchers and practitioners.

“…Hyperventilation is now known to contribute to conditions including anxiety disorder and asthma [140][141][142][143]. Patients with hyperventilation and breathing pattern disorders demonstrate chronic abnormalities in breathing control and increased responses to CO 2 ( Figure 5) [144,145].…”

Four phenotypes of obstructive sleep apnea hypopnea syndrome (OSAHS) have been identified. Only one of these is anatomical. As such, anatomically based treatments for OSAHS may not fully resolve the condition. Equally, compliance and uptake of gold-standard treatments is inadequate. This has led to interest in novel therapies that provide the basis for personalized treatment protocols. This review examines each of the four phenotypes of OSAHS and explores how these could be targeted using breathing re-education from three dimensions of functional breathing: biochemical, biomechanical and resonant frequency. Breathing re-education and myofunctional therapy may be helpful for patients across all four phenotypes of OSAHS. More research is urgently needed to investigate the therapeutic benefits of restoring nasal breathing and functional breathing patterns across all three dimensions in order to provide a treatment approach that is tailored to the individual patient.

“…Dysfunctional, inefficient breathing patterns are especially prevalent in adults with COPD. [58][59][60] They include such patterns as hyperventilation, thoracic dominant breathing, tachypnea, open-mouth breathing, thoracoabdominal asynchrony, and deep sighing. 58 By addressing dysfunctional behavioral breathing habits, CART may reduce physiological impairment (hypocapnia, hypercapnia, lung hyperinflation, impaired respiratory muscle function, and inefficient recovery from a breathing challenge) associated with both dyspnea and comorbid anxiety.…”

Acceptability of capnography-assisted respiratory therapy: a new mind–body intervention for COPD

et al. 2021

Dyspnea self-management is often suboptimal for patients with chronic obstructive pulmonary disease (COPD). Many patients with COPD experience chronic dyspnea as distressing and disabling, especially during physical activities. Breathing therapy is a behavioral intervention that targets reducing the distress and impact of dyspnea 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-centered biofeedback, tailored breathing exercises, home exercise program, and motivational interviewing counseling. 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 behaviors and dysregulated interoception, CART offers a promising new paradigm for relieving dyspnea and related anxiety in patients with COPD.
