Abstract

Purpose: To study the effects of breathing exercises on preventing pulmonary complications in patients undergoing coronary artery bypass graft surgery.

Methods: Observing whether preoperative breathing exercises can reduce the incidence of postoperative pulmonary complications in patients undergoing coronary artery bypass graft surgery; observing whether these exercises can improve postoperative arterial oxygen pressure, oxygen saturation, and the distance walked in a six-minute walk test after surgery; as well as reduce hospital stay duration, lower treatment costs, and improve the quality of life as measured by the Short Form-36 Health Survey (SF-36).

Design: The study population includes patients undergoing coronary artery bypass graft surgery under general anesthesia; the research center is Capital Medical University Xuanwu Hospital; the sample size is 120. Preoperative standardized breathing exercises are utilized, and the incidence of postoperative pulmonary complications, postoperative arterial blood gases, oxygen saturation, six-minute walk test distances, and comparisons of hospital stay durations and costs will be observed.
