Effects of Breathing Exercises With and Without Inspiratory Muscle Training in COPD Patients

Participants will be guided to adopt a deep breathing practice by emphasizing the use of the diaphragm muscle, thereby minimizing the contribution of accessory muscles during inspiration. This approach fosters the efficiency of respiratory mechanics, aiding in the mitigation of dyspnea symptoms. Participants are directed to undertake these exercises 2-3 times per day, dedicating 15-20 minutes per session, consistently over a period of 2 months. Pursed-Lip Breathing .This technique involves exhaling through semi-closed lips, creating a resistance that helps control the rate of exhalation and, thus, optimizes lung volumes and capacities. This exercise is recommended to be performed similarly to diaphragmatic breathing, 2-3 times daily for 15- 20 minutes per session for a period of 2 months

The resistance on the BREATHER device will be adjusted to match each participant's abilities and progression. The resistance level will be challenging yet manageable, ensuring participant comfort. Each daily session will consist of 15-30 minutes with the BREATHER device and can be split into two shorter sessions if necessary. The total duration of this treatment protocol will span 2 months. The BREATHER device will be employed for both inspiratory and expiratory muscle training. Alongside the device usage, specific breathing exercises, such as diaphragmatic and pursed lip breathing, will be performed
