Background: Coronary artery bypass graft considered one of the most common surgical procedures that are performed worldwide to treat complications for patients with ischemic heart disease. Appropriate positioning of the patient post cardiac surgery cans dramatically improved blood oxygenation, prevent atelectasis and improve the hemodynamic status. The aim of this study was to evaluate the effect of supine versus semi-setting positioning on physiological indices among patients' post-CABG. Design: A quasi-experimental research design was utilized. Setting: Surgical ICU at International Educational Hospital in Tanta University Hospitals, Egypt. Subjects: A purposive sample of (80) patients was enrolled in the current study and dividid equally into supine and semi-fowler groups. Tools: Two tools were used to collect data; Tool (I): Patient's bio-socio-demographic data and Tool (II): Cardiorespiratory parameters. Results: The study findings revealed that there was statistically significant improvement regarding total mean scores of respiratory rate, PaO2, PaCO2, and SpO2 among patients in semi-setting than the supine group in which P < 0.05. Conclusion: it was concluded that the application semi-setting positions for patient's post coronary artery bypass graft had a significant positive improvement of physiological indices especially respiratory parameters compared to supine position. It is recommended that semi-setting positioning should be integrated into routine care for critically ill patients post-CABG.
