ObjectiveTo observe the effects of staged training theory-guided breathing training on cardiopulmonary function, mental resilience, and inflammatory factors in patients with chronic obstructive pulmonary disease (COPD). MethodA total of 93 patients with COPD were randomly divided into a control group (46 cases) or an observation group (47 cases). The control group received conventional treatment, health education, and routine breathing training, based on which the observation group received staged training theory-guided breathing training, and both groups were intervened for 8 weeks. The cardiopulmonary function, mental resilience, and inflammatory factors levels after 8 weeks of intervention were compared between the two groups. ResultsAfter 8 weeks of intervention, the observation group had higher forced vital capacity (FVC), 1s forced expiratory volume (FEV1), FEV1/FVC, peak oxygen uptake, oxygen consumption at anaerobic threshold, and Connor-Davidson Resilience Scale′s hardiness, adaptation, and stress endurance dimensions scores, but lower minute ventilation-to-carbon dioxide output slope and peripheral blood tumor necrosis factor-α and interleukin-6 levels than the control group (all P＜0.05). ConclusionStaged training theory-guided breathing training can effectively improve cardiopulmonary function and mental resilience and reduce the inflammatory factors levels in COPD patients.
