The effect of slow deep breathing relaxation exercise on pain levels during and post chest tube removal after coronary artery bypass graft surgery.

Objectives: This study aimed to evaluate the effectiveness of slow deep breathing relaxation exercise (SDBRE) in reducing patients' pain levels during chest tube removal (CTR) post coronary artery bypass grafting (CABG) surgery.

Methods: In 2019, fifty post-CABG patients were conveniently selected from a cardiac intensive care unit in Jordan's major referral heart institute. The patients were randomly assigned to either an intervention group or a control group.
