Summary

Background: Incentive spirometry is used in addition to care, especially in reducing pulmonary complications after surgery. Complications in the cardiovascular and pulmonary systems can basically be determined by blood values and vital signs, which are important objective data of haemodynamics.

Aim: This study was designed to test the hypothesis that the use of incentive spirometry in conjunction with postoperative pulmonary rehabilitation care has a notable impact on arterial blood gas, oxygen saturation (SpO2), and vital signs.

Methods: This randomised, controlled trial was designed using a repeated-measures design. The study was planned to be conducted at the cardiovascular surgery clinic of a university hospital. It was intended that data from patients undergoing coronary artery bypass graft surgery would be analyzed. All patients were planned to receive routine pulmonary rehabilitation, with incentive spirometry added for the experimental group. Outcome measures were designed to include arterial blood gas values, oxygen saturation, and vital signs recorded during the postoperative period.

Interventions

DEVICE

Incentive Spirometry Group

A flow-oriented incentive spirometer with three compartments and target volumes of 600, 900, and 1200 mL was used. Patients were instructed in its use preoperatively and continued the application after extubation when fully awake. The intervention was performed every 1 to 2 hours while awake, for a total of 10 to 20 breaths according to tolerance. Patients performed deep breathing exercises first, followed by incentive spirometry, and then coughing exercises. During the application, the bed was elevated to 45 degrees and the patient was positioned in long sitting. Patients were instructed to inhale slowly and deeply to raise the balls to the target level, hold their breath for 3 to 5 seconds, and then exhale normally. The exercise was repeated according to tolerance, and coughing exercises were performed after every five repetitions.
