“…(Elbehairy et al, 2016; Di Marco et al, 2017) These physiological considerations should be tempered with the observation that smokers have two to four times more panic-depression and anxiety disturbances compared to controls (Zvolensky et al, 2004; Moylan et al, 2012; Fadda et al, 2013). These abnormalities are associated with a chaotic breathing pattern and hyperventilation sindromes (Bokov et al, 2016; Bansal et al, 2018), and accordingly, contemporary models of fatigue point out to complex interactions between physiological activity and psychological state (Gruet, 2018). Hence, such complex “coordinated deadaptation”(Burtscher, 2013) in symptomatic smokers might lead to perceived fatigability (sensations about fatigue) and performance fatigability (incapacity of the neuromuscular system to meet the requirements of a given task) (Enoka and Duchateau, 2016).…”

Cardiopulmonary and Muscular Interactions: Potential Implications for Exercise (In)tolerance in Symptomatic Smokers Without Chronic Obstructive Pulmonary Disease

Smoking and physical inactivity are important preventable causes of disability and early death worldwide. Reduced exercise tolerance has been described in smokers, even in those who do not fulfill the extant physiological criteria for chronic obstructive pulmonary disease (COPD) and are not particularly sedentary. In this context, it is widely accepted that exercise capacity depends on complex cardio-pulmonary interactions which support oxygen (O 2 ) delivery to muscle mitochondria. Although peripheral muscular factors, O 2 transport disturbances (including the effects of increased carboxyhemoglobin) and autonomic nervous system unbalance have been emphasized, other derangements have been more recently described, including early microscopic emphysema, pulmonary microvascular disease, ventilatory and gas exchange inefficiency, and left ventricular diastolic dysfunction. Using an integrative physiological approach, the present review summarizes the recent advances in knowledge on the effects of smoking on the lung-heart-muscle axis under the stress of exercise. Special attention is given to the mechanisms connecting physiological abnormalities such as early cardio-pulmonary derangements, inadequate oxygen delivery and utilization, and generalized bioenergetic disturbances at the muscular level with the negative sensations (sense of heightened muscle effort and breathlessness) that may decrease the tolerance of smokers to physical exercise. A deeper understanding of the systemic effects of smoking in subjects who did not (yet) show evidences of COPD and ischemic heart disease – two devastating smoking related diseases – might prove instrumental to fight their ever-growing burden.

“…In particular, CPET can detect chronic hyperventilation syndrome and ventilatory irregularity (corresponding to periodic deep sighing in the Boulding classification) as limitations to exercise capacity. 12,13 CPET studies of patients post-COVID have similarly shown a high prevalence of BPD, 14,15 but CPET is resource-intensive, limiting its use in the assessment of large numbers of patients in long COVID clinics.…”

Real-world use of the Breathing Pattern Assessment Tool in assessment of breathlessness post-COVID-19

Patients undergoing face-to-face review in a post-COVID clinic were assessed by a respiratory physician and specialist respiratory physiotherapist. Assessment included a Dyspnoea-12 (D12) questionnaire to assess breathlessness, physiotherapist assessment of breathing pattern including manual assessment of respiratory motion, and BPAT assessment. The sensitivity and specificity of BPAT for diagnosis of BPD in post-COVID patients was assessed. ResultsBPAT had a sensitivity of 89.5% and specificity of 78.3% for diagnosing BPD in post-COVID breathlessness. Patients with a BPAT score above the diagnostic cut-off had higher levels of breathlessness than those with lower BPAT scores (D12 score mean average 19.4 vs 13.2). ConclusionBPAT has high sensitivity and moderate specificity for BPD in patients with long COVID. This would support its use as a screening test in clinic, and as a diagnostic tool for large cohort studies.

“…Before the formal implementation of sports rehabilitation training, it was necessary to evaluate the symptoms, sports ability, quality of life, mental state and other aspects. Bansal’s team [ 67 ] evaluated the performance of 20 adults with disordered breathing on an incremental cardiopulmonary exercise test. It found that VO 2 max was lower than average and that patients more frequently cited dyspnea as the cause of their exercise limitations.…”

As a global pandemic, COVID-19 shows no sign of letting up. With the control of the epidemic in China, the proportion of patients with severe and critical diseases being cured and discharged from hospital has increased, and the recovery of COVID-19 patients has become an important issue that urgently needs attention and solutions. By summarizing the exercise rehabilitation strategies and progress of SARS in 2003, this paper analyzed the differences in clinical indicators and recovery characteristics of severe pneumonia caused by the two viruses, and provided comprehensive exercise guidance and intervention strategies for COVID-19 patients for rehabilitation and nursing by referring to the problems and treatment strategies in the rehabilitation and nursing work of SARS. In the post-epidemic period, China will build a multi-dimensional epidemic prevention system by improving the effectiveness of mass training and strengthening local risk prevention and control. This paper discusses the exercise rehabilitation strategy of SARS patients after recovery, which has guiding significance for exercise intervention and scientific fitness of COVID-19 patients after recovery during epidemic prevention period.

Exercise ventilatory irregularity can be quantified by approximate entropy to detect breathing pattern disorder

Abstract: Non-linear statistical interrogation of CPET-acquired ventilatory data has utility in the detection of BPD. A simple calculation of approximate entropy of ventilation, during an incremental cardiopulmonary exercise test, provides a quantitative method to detect BPD.
