A study concluded that preoperative Inspiratory Muscle Training (IMT) reduced the incidence of Postoperative pulmonary complications and duration of postoperative hospitalization in patients at high risk of developing a pulmonary complication undergoing CABG surgery1.
Another study concluded that Inspiratory Muscle Training (IMT) for 2-4 weeks before coronary artery bypass graft surgery was well tolerated by patients at risk of postoperative pulmonary complications and prevented the occurrence of atelectasis in these patients. A larger randomized clinical trial is warranted2.
