<![CDATA[Background: His WHO data for 2019 puts him third in COPD deaths, at about 3.23 million. Decreased respiratory function is one of the symptoms of COPD that causes respiratory arrest that impacts quality of life. Pulmonary rehabilitation in COPD patients is a means of controlling and reducing symptoms and optimizing functional function.Method: Experimental study with pre-test and post-test groups design. The number of study participants was 30 stable COPD outpatient in group B and E of the Respiratory Clinic of the UNS Hospital during the period of February 2023 by targeted sampling. The control group (n = 15) received standard care and the treatment group (n=15) received standard care plus additional balloon-inflation exercises for 6 weeks. Comparisons between pretest and posttest groups were made on %VEP1 score, breathlessness symptoms, CAT questionnaire, exercise capacity, and EID.Result: Increased values of %VEP1 (p=0.001), decreased Borg scale (p=0.001), decreased CAT score (p = <0.001), and physical activity performance (p = 0.001) versus his EID (p = <0.001) increase.Conclusion: Inflating the balloon affects %VEP1, Borg scale, CAT score, training capacity increase, and EID values. Balloon blowing exercise increases the %VEP1 value, lowers the Borg scale, lowers the CAT score, increases exercise capacity, and EID.Keywords: %VEP1, Borg scale, training capacity, CAT, EID]]>
