Comparison between deep breathing exercises and incentive spirometry after CABG surgery.
OBJECTIVE To compare the effects of deep breathing exercises ( DBE ) and the flow-oriented incentive spirometry ( IS ) in patients undergone coronary artery bypass grafting ( CABG ) through the following variables : forced vital capacity - FVC , forced expiratory volume in 1 second - FEV(1 ) , maximal respiratory pressures and oxygen saturation . METHODS Thirty six patients in CABG postoperative period underwent thirty minutes of non-invasive ventilation  during the first 24 hours after extubation and were r and omly shared into two groups as following : DBE ( n=18 ) and IS ( n=18 ) . The spirometric variables were assessed on the preoperative period and seventh postoperative day ( POD ) . The respiratory muscle strength and oxygen saturation were assessed on the preoperative period , first , second and seventh POD . RESULTS The groups were considered homogeneous in relation to the demographic and surgical variables . It has been noted fall in the values of FVC and FEV(1 ) between the preoperative period and the seventh POD , but without significant differences between groups . The maximal respiratory pressures showed drop in the first POD but with and partial recovery until the seventh POD , also without significant differences between groups . The oxygen saturation was the only variable that was completely recovered on the seventh POD , also without significant differences between groups . CONCLUSION There were not observed significant differences in maximal respiratory pressures , spirometric variables and oxygen saturation in patients undergone deep breathing exercises and flow-oriented incentive spirometry after coronary artery bypass grafting
