A Minimal-Risk, Multi-Center, Prospective, Clinical Trial to Evaluate the PrevisEA Device for Predicting Gastrointestinal Impairment


This device listens to and records abdominal sounds, which provides data that can help predict gastrointestinal impairment (GII). GII is a condition that is defined as the failure of oral re-feeding after abdominal surgery. This happens when any of the following events happen beyond 24-hours after abdominal surgery; vomiting, need to reverse the diet, or need to place a nasogastric (NG) tube.
