Predicted postoperative FEV1- not correct to use!!!

Predicted postoperative FEV1 is the most widely used parameter in preoperative risk calculation in the screening of patients for lung resection surgery.
Recent evidences have suggested that predicted postoperative FEV1 is not a reliable predictor of postoperative cardiopulmonary complications because of the fact that the resection of a portion of lung in patients with obstructive disease determines only a minimal loss.
The FEV1 measured on the first postoperative day may be 30% less than predicted postoperative FEV1.
