Sponsor's own description

Open cardiac surgery is an important treatment method that is frequently used in the treatment of complicated atherosclerotic ischemic heart disease and heart valve diseases.

It is emphasized that respiratory functions decrease significantly after cardiac surgery, especially in the immediate post-operative period. Therefore, despite significant progress in the field of cardiopulmonary bypass and anesthesia technique, pulmonary complications after cardiac surgery are still seen as the main cause of other negative outcomes such as morbidity, mortality, and long-term hospitalization.

Cardiac surgery patients are especially at high risk for the development of postoperative pulmonary complications (PPC).

It has been reported that deep breathing exercises improve postoperative lung expansion and ventilation, resulting in a significant reduction in pulmonary complications.

Postoperative respiratory physiotherapy techniques include techniques such as early mobilization, positioning, breathing exercises, active breathing techniques cycle, as well as the use of different mechanical devices such as incentive spirometry (IS), positive expiratory pressure mask therapy, and continuous positive airway pressure. Incentive spirometry (IS) is a mechanical breathing device that provides slow deep breathing and gives visual feedback and is used as one of the important interventions in the prevention of PPC in patients who have been undergoing open heart surgery for many years.

In studies examining the effectiveness of deep breathing exercise with IS on the development of PPC in open cardiac surgery patients, it is seen that IS application is performed in the postoperative period , it is noteworthy that there is no study examining the effectiveness of preoperative IS application. In the light of this information, the aim of this study is to evaluate the effect of deep breathing exercise with incentive spirometry initiated in the preoperative period on pulmonary function and complications in patients undergoing open heart surgery.
