Coronary artery bypass graft surgery (CABG) is associated with postoperative respiratory depression. In this study we aimed at investigating perioperative parameters that could predict the nadir of postoperative respiratory function impairment.
Coronary artery bypass graft (CABG) surgery is a principal revascularization option for ischemic heart disease and the principal modality for invasive treatment of coronary artery disease. Postoperative pulmonary complications are the most frequent and significant contributor to length of hospitalization, morbidity and mortality. The objective of this study is to search for perioperative parameters that could predict the degree of impairment of respiratory function after CABG with cardiopulmonary bypass (CPB).

Postoperative Respiratory Depression After Cardiac Surgery
Respiratory function is assessed through maximal inspiratory (MIP) and expiratory (MEP) pressures and peak expiratory flow (PEF) determined 1 day before surgery and one postoperative week.
Time frame: 9 days
Intraoperative parameters after coronary artery bypass graft surgery (CABG)
Intraoperative parameters are monitored, including volume of cardioplegia, CPB duration, aortic cross-clamp time, number of grafts.
Time frame: 1 day
Perioperative parameters after coronary artery bypass graft surgery (CABG)
ICU blood pressure is monitored
Time frame: 3 days
