Patients undergoing cardiac surgery remain on mechanical ventilation postoperatively until they regain consciousness. Positive end-expiratory pressure (PEEP) may influence the duration of after coronary artery bypass grafting (CABG). The aim this study was to compare effects different levels PEEP grafting. This a randomized clinical trial with 136 patients CABG between January 2011 and March 2012. We divided into three groups at onset ventilation: Group A, = 5 cmH2O (n 44); B, 8 47) C, 10 45). Mechanical time obtained from Physical Therapy Evaluation Form. excluded chronic obstructive pulmonary disease those requiring concomitant, emergency or off-pump surgeries. For statistical analysis, we used Kruskal-Wallis, G Chi-square tests, p <0.05 considered significant. From point weaning 12 hours intensive care unit (ICU) admission, saw statistically (p 0.029). In average 6.7 ± 3.2 hours; it 6.8 3.3 in B 5.1 2.9 C. use higher associated shorter postoperative patients.
