Summary

This study aims to investigate the effects of diaphragm relaxation technique on sleep quality and respiratory functions in patients who have undergone coronary artery bypass graft (CABG) surgery. Two groups will be formed in the study: one group will receive standard cardiac rehabilitation, while the other group will receive diaphragm relaxation technique in addition to this. Throughout the study, patients' respiratory functions, sleep quality, respiratory muscle strength, and pain levels will be measured. These measurements will be taken from the patients...

Detailed description

This study is an interventional research investigating the effects of the diaphragm release technique on sleep quality and respiratory functions in patients undergoing minimally invasive coronary artery bypass graft (CABG) surgery. Participants will be assigned to either an intervention or a control group. Both groups will receive standard in-hospital cardiac rehabilitation, while the intervention group will additionally receive the diaphragm release technique during their hospital stay. Data will be collected using standardized tools, including pulmonary function tests (spirometry), respiratory muscle strength measurements, the Pittsburgh Sleep Quality Index, and visual analog scales for pain assessment. Written informed consent will be obtained from all participants, and the study will be conducted at Gaziantep Sanko University Hospital Cardiovascular Surgery Unit in accordance with ethical committee approval. The aim of this research is to develop a safe and effective method to improve respiratory health and quality of life in patients after cardiac surgery.

Conditions

• Coronary Artery Bypass
• Cardiac Rehabilitation

Interventions

Type	Name	Description
OTHER	Intervention Group	Participants receive standard in-hospital cardiac rehabilitation plus diaphragm release technique. The diaphragm release is performed daily during the hospital stay for a minimum o
OTHER	Control Group	Participants receive standard in-hospital cardiac rehabilitation only, including breathing exercises, mobilization, and post-operative physiotherapy, without diaphragm release.
