Chronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory disease that causes a decline in pulmonary ventilation function. This study aimed to determine the effect of Respiratory Muscle Training using the Pursed-Lips Breathing technique on pulmonary ventilation function in patients with COPD at Advent Hospital Bandar Lampung in 2025.  This study used a quantitative approach with a pre-experimental method and a one-group pretest–posttest design. A total of 32 COPD patients were selected using purposive sampling. Pulmonary ventilation function was measured before and after the intervention using a peak flow meter and analyzed using the Wilcoxon test. The results showed a significant improvement in pulmonary ventilation function after the intervention (p < 0.001). It was concluded that the Pursed-Lips Breathing technique is effective in improving pulmonary ventilation function in patients with COPD. This method can be considered a non-pharmacological intervention to improve pulmonary ventilation function.
