NCT05948891
This is an observational, prospective, multicentric, cohort study conducted in France to evaluate the QoL in COPD patients treated with TRIMBOW NEXThaler 88/5/9 in a routine clinical practice setting. Patients enrolled in this study will be patients diagnosed with a COPD with a ratio of post-bronchodilator (salbutamol 400 μg) forced expiratory volume in 1 s (FEV1) to forced vital capacity (FVC) of less than 0.7 to whom TRIMBOW NEXThaler 88/5/9 has been initiated by an hospital or local pulmonologists in accordance with clinical practice and marketing authorization.

Inspiratory muscle training has been an important part of pulmonary rehabilitation program directed at patients with COPD. It can increase respiratory muscle strength, relieve dyspnea ,improve the quality of life in COPD patients. However, there is no uniform standard for the intensity of inspiratory muscle training. By comparing a series of indexes, such as maximal inspiratory pressure, maximal expiratory pressure, degree of dyspnea and exercise capacity before and after the training under different intensity, a large number of literatures have explored the appropriate intensity of inspiratory muscle training. But to date, there are few studies about the effects of different intensity of inspiratory muscle training on respiratory physiological mechanism. It has been shown that inspiratory muscle training may be more beneficial to improve the pulmonary rehabilitation effect of COPD patients with inspiratory muscle weakness. So it is not clear whether there is a difference in respiratory physiology between patients with normal inspiratory muscle strength and those with lower inspiratory muscle strength. Respiratory central drive, as an important physiological index, which can be reflected by minute ventilation volume, mouth pressure, mean inspiratory flow and diaphragm electromyography,is closely related to the symptoms and the severity of the disease.Therefore,the purpose of this study was to investigate the changes of respiratory mechanics and central drive in COPD patients at different inspiratory loads, and at the same loads between patients with and without respiratory muscle weakness.That can provide more evidential evidence for setting up the intensity of inspiratory muscle training.
