- Primary Outcome Measures
Name Time Method The pre- and postoperative instruction of breathing therapy exercises using EIT as biofeedback in patients with general upper abdominal surgery (arm 1) increases the oxygen saturation under room air on the second postoperative day from an average of 94% (+/- 3) to 98% (+/- 1) in comparison to otherwise identically treated patients only without EIT as biofeedback (arm 2) and can thus contribute to the reduction of PPC.
