Abstract
Background and purpose: Pulmonary complications are among the most frequently reported complications after Coronary Artery Bypass Graft (CABG) surgery. However, the risk of postoperative pulmonary complications is not equal for all patients. In the intensive care unit, patients have different adherence to two commonly used positive-expiratory-pressure (PEP) therapy devices: the PEP mouth piece and the PEP mask. The reason for this difference is not clear. The aim of this study was to investigate outcome measures of two different positive end expiratory pressure applications post CABG surgery. Subjects and Methodology: Sixty male and female patients who underwent off pump CABG aged from 40-60 years old and recruited from the National Heart Institute enrolled in that study for two weeks. They were assigned into three matched groups: group (A): Consisted of 20 patients, which received PEP with face mask group (B): Consisted of 20 patients, which received PEP with mouth piece. group (C): The control group consisted of 20 patients, which received routine cardiac rehabilitation physiotherapy program (postural drainage, percussion, vibration, deep breathing exercises, arm ergometer, acupuncture like TENS, gait training). The program continued for two weeks. Data obtained from the three groups at the beginning of the study and after the end of two weeks regarding respiratory muscle strength (Maximum Inspiratory pressure MIP, maximum expiratory pressure MEP), Six-minute walking distance and dyspnea scale were statistically analyzed and compared
