Abstract

Background: Coronary artery disease] CAD [causes significant respiratory, medical, and physical problems affecting the quality of life [QoL [. Quake device, one of the oscillatory positive expiratory pressure [OPEP] family, may improve the health of patients with CAD, but more research is needed.
The Aim of the work: The main aim of this study was to examine the effects of intra-thoracic oscillations on blood gases after coronary artery bypass graft surgery [CABG].
Patients and Methods: The research included a cohort of 60 male individuals who had the surgical procedure known as Coronary Artery Bypass Grafting [CABG] aged 55–65; they were recruited from the 6 October hospital. The patients were divided equally into groups A and B; group A included patients who underwent therapy with OPEP using the Quake device in conjunction with conventional and medically recommended therapies; group B included patients treated by traditional treatment and their prescribed medical treatment. Both treatments were performed once daily from the first day till the seventh day after operation. They were evaluated using Arterial Blood Gases [ABG], the sit-to-stand test, and the [SF-36] QoL questionnaire.
Results: The previous and post-study comparison revealed a significant enhancement in both groups of ABG values [PH, PaO2, PaCO2, and HCO3] and, the sit-to-stand test and SF-36 questionnaire. The study group had a statistically significant advantage over the control group when comparing all assessed post-treatment parameters to those of the control group.
Conclusion: Early rehabilitation after CABG surgery via Quake device could improve ABG, patient's functional capacity,reflecting a better QoL.
