Forced expiratory flow-volume relationships. Changes after upper abdominal surgery.
Forced expiratory flow-volume relationships have been used to investigate changes in lung mechanics caused by upper abdominal operations. The slope of the 'effort independent' portion of the flow-volume curve increases after operation, suggesting that restriction of respiratory movement is associated with an increase in lung recoil.
