This study aims to evaluate the effectiveness of an innovative inhaler training device, "Golden Rhino" (pMDI Practice Tool), in improving inhalation technique accuracy, dyspnea severity, and quality of life among elderly patients with chronic obstructive pulmonary disease (COPD). The device integrates a weighted valve and musical cues to guide patients in synchronizing their breath with proper pMDI inhalation technique. Participants will be randomly assigned to either standard nursing guidance or nursing guidance plus device-based training. Outcome measures include pMDI usage accuracy, dyspnea severity, and EQ-5D quality of life scores at baseline and follow-up.
