Intelligent Pulmonary Rehabilitation After Lung Cancer Surgery

Starting soon · Not applicable

Conditions studied: Non-Small Cell Lung Cancer

In brief

This study will compare an intelligent pulmonary function exercise device with usual care and natural recovery in patients recovering from lung cancer surgery. After lung cancer surgery, many patients have reduced lung function, shortness of breath, lower exercise tolerance, and a risk of postoperative pulmonary complications. Standard care usually includes postoperative nursing, pain control, coughing and sputum clearance instruction, early mobilization, discharge education, and routine follow-up. However, patients often lack structured guidance, feedback, and monitoring after discharge. Participants in this study will be randomly assigned to one of two groups. One group will use an intelligent pulmonary function exercise device for respiratory training during hospitalization and at home until 30 days after surgery. The prescribed training is two sessions per day, with each session including 30 expiratory training repetitions and 30 inspiratory training repetitions. The device records training completion and related training information and provides reminders and feedback. The other group will receive usual perioperative care, standard discharge education, and natural recovery follow-up without a study-specified respiratory training device or training prescription. The main purpose of the study is to determine whether the intelligent pulmonary function exercise device improves recovery of forced expiratory volume in 1 second, or FEV1, from before surgery to 30 days after surgery. The study will also evaluate lung function at 90 days, symptoms, quality of life, walking capacity, training adherence, and postoperative complications.
