Chronic obstructive pulmonary disease (COPD) poses a serious threat to global public health and has become the fourth leading cause of death worldwide. It is a common chronic disease characterized by airflow obstruction, including chronic bronchitis and/or emphysema, which can further progress to cor pulmonale and respiratory failure.

Inclusion criteria
Inclusion criteria: 1.According to the diagnostic criteria of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2025, the diagnosis of COPD is confirmed based on the presence of persistent respiratory symptoms (such as cough, sputum production, dyspnea) and a clear history of exposure to risk factors (such as smoking, biomass fuel exposure), along with pulmonary function testing showing a ratio of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) of = 10 was defined as significant impact), ensuring that the study subjects had a clear need for pulmonary rehabilitation. 3.Patients aged >= 40 years, consistent with the high-risk age range for COPD, and in a stable phase of the disease (no history of acute exacerbation in the past 3 months), defined as the absence of acute events such as worsening dyspnea requiring hospitalization, increased sputum volume, or changes in sputum properties, so as to avoid interference from acute inflammatory status on the effects of breathing training. 4.Availability of complete clinical training records and pre- and post-training assessment data.
Exclusion criteria
Exclusion criteria: 1.Patients were excluded if they had coexisting severe cardiovascular or cerebrovascular diseases (such as unstable angina pectoris, recent myocardial infarction, severe arrhythmias, or cardiac function class ? or above) or malignant tumors, as these conditions might limit exercise tolerance or pose training-related risks, potentially leading to bias in the study results. 2.Patients were excluded if they had moderate or severe cognitive impairment (Alzheimer's disease, vascular dementia) or psychiatric disorders (schizophrenia), to avoid interference with the evaluation of intervention effects due to inability to understand training instructions or cooperate with the procedures. 3.Patients were explicitly excluded if they had pneumothorax, pulmonary bullae (>= 3 cm in diameter or with tension characteristics), uncontrolled hemoptysis, acute pulmonary embolism, or other such conditions, as traditional breathing training or pressure feedback from smart devices might increase the risk of alveolar rupture or hemodynamic instability.
