Pengaruh Breathing Retraining Terhadap Peningkatan Fungsi Ventilasi Paru Pada Asuhan Keperawatan Pasien PPOK

The aim of the research was to explain about the influence of breathing retraining to the increasing of lung ventilation function for nursing care of theCOPD patients at a Hospital in Jakarta. The reseach design was quasi experiment with control group pretest-postest design. Total 34 patients (17 subjects for each group, intervention and control group) were included by a simple random sampling method. A breathing retraining was given to the intervention group for 6 days. The finding showed that the average of the COPD patient\u27s lung ventilation was significantly different before and after breathing retraining (p value = 0.000). The average score of the COPD patient\u27s lung ventilation after breathing retraining between intervention group and control group was also significantly different (p value = 0.012). There was significant relationship between age and increased lung ventilation function (p value = 0.001). However, no relationship found between body height and increased lung fuction (p value = 0.091) and between gender and lung ventilation function (p value = 0.346). The research suggested to implement the breathing retraining to increase the lung ventilation function of the CPOD patients
