Abstract: Coronary artery disease is the main contributing factor for death globally. Despite advancement and highly used of technology in surgical procedures, anesthesia and health care plans and interventions established for patients post open heart surgery, postoperative pulmonary complications are considered one of the major complications leading to severe morbidity and mortality. After a thorough review of the literature regarding predictors of pulmonary complications following CABG surgery, a retrospective study was conducted to identify and types, incidence and predictors of pulmonary complications post CABG surgery among Jordanian patients. A descriptive retrospective design was used to collect data from medical records of 150 Jordanian patients whose ages are 25 years old or above and 1st time undergoing CABG surgery. The main results of the study included that 60% of the sample studied developed pulmonary complications during the first week post CABG surgery. The most predominant PPCs were plural effusion (42.7%), atelectasis (33.3%) and pulmonary edema (16.7%). The most predictors of PPCs were hypertension, obesity, length of hospital stay.
