Utilizing OPEP Devices, Reduce Post-operative Complications Related to Pulmonary Function following Coronary Artery Bypass Graft Surgery: Evidence-Based Study

Background: The most common and major cause of hospitalization-related morbidity, mortality, and expenses is postoperative pulmonary problems. Patients receiving CABG have a high risk of developing post-operative pulmonary problems. Members of the oscillatory positive expiratory pressure [OPEP] family may benefit from this treatment. Objective: The purpose of this literature review is to enhance knowledge regarding the function of OPEP devices and their relationship to post-operative pulmonary complications following CABG. Method: From January 2009 to December 2023, pertinent keywords will be employed for the research using the electronic databases PubMed, Medline and Google Scholar. Bibliographic information and associated research materials were managed using Zotero, an open-source reference management programme. Result: databases including PubMed, Medline, and Google Scholar, where 12 studies that initially passed the inclusion criteria were examined and included. A total of 27,689 citations were evaluated in PUBMED, GOOGLE SCHOLAR, and MEDLINE between January 2009 and December 2023. Following the application of inclusion/exclusion criteria, which included full text and abstract screens, 27,677 articles were discarded throughout the data extraction process. Conclusion: Research has demonstrated the effectiveness of OPEP devices in treating a variety of respiratory illnesses; however, less research has been done on the use of OPEP devices in patients after heart surgery. Thus, the study's objective is to assess the accuracy, desired outcome, and necessary knowledge of OPEP devices as well as their efficacy. KEY WORDS: CABG, OPEP Devices, Pulmonary Complications.
