Active Cycle of Breathing Techniques on Respiratory Distress Symptom Cluster

The sample of the study will consist of patients who received chemotherapy treatment with the diagnosis of Stage IV non-small cell lung cancer in the outpatient chemotherapy service of a training and research hospital and met the inclusion criteria. Data in the study will be collected using the Patient Information Form, Eastern Cooperative Oncology Group (ECOG) Performance Scale, Cancer Dyspnea Scale, Leicester Cough Questionnaire and Cancer Fatigue Scale. In order to test the applicability and comprehensibility of the forms to be used before the study, a preliminary application will be made with 5 patients. This study is planned to prepare a video describing the application for patients to use while performing the Active Cycle of Breathing Techniques application. On the 1st day of the study, a 10-minute face-to-face training will be given to the intervention (experimental) group by the researcher using the video about the Active Cycle of Breathing Techniques. In the research, the intervention (experimental) group will be asked to follow the video to be prepared and apply the Active Cycle of Breathing Techniques twice a day for 28 days. The intervention (experimental) group will be monitored by telephone call once a week and 3 times using the Patient Follow-up Form (days 7, 14 and 21). On the other hand, only the pre-test and post-test will be applied to the control group.
