[ABSTRAK
Keluhan utama yang paling sering dirasakan pasien PPOK adalah sesak. Salahsatu intervensi keperawatan untuk meningkatkan kepercayaan diri dalam upayamengatasi sesak pasien PPOK adalah efikasi diri pursed lip breathing. Penelitianini bertujuan mengetahui pengaruh efikasi diri pursed lip breathing terhadappenurunan sesak dan peningkatan saturasi oksigen pasien PPOK. Desainpenelitian adalah randomized controlled trial dengan rancangan penelitianpretest-postest design. Penelitian ini melibatkan 36 responden denganmenggunakan teknik randomisasi blok terbagi menjadi 18 responden kelompokintervensi dan 18 responden kelompok kontrol. Hasil analisis statistik didapatkanbahwa terdapat perbedaan yang bermakna penurunan sesak dan peningkatansaturasi oksigen antara kelompok intervensi dan kelompok kontrol setelahintervensi dengan nilai p < 0.001. Efikasi diri pursed lip breathing dapat dijadikansalah satu alternatif intervensi keperawatan manajemen jalan napas pada pasienPPOK.

ABSTRACT
The main complaints are most often perceived COPD patient is dyspnea. One ofnursing interventions to increase self confidence in the effort to overcome thedyspnea of COPD patients are self-efficacy of pursed-lips breathing. This studyobjective was to see the influence of self-efficacy of pursed-lips breathing ondyspnea reduction and oxygen saturation increase in COPD patients. Arandomized controlled trial with pretest-postest method were used as the studydesign. This study involved 36 respondents divided into intervention and controlgroup by block randomization. The statistic analysis result shows a differencebetween the two groups after the interventions were made which means therewere dyspnea reduction and oxygen saturation increase at value p < 0.001. selfefficacyof pursed-lips breathing can be applied as one of alternative nursingintervention for COPD airway management, The main complaints are most often perceived COPD patient is dyspnea.
