Evaluation of the PrevisEA Device for Predicting Gastrointestinal Impairment

The PrevisEA device is placed and activated on the patient's abdomen immediately post-op (within 1 hour of the completion of surgery) and maintained in position for at least 12 hours, counting the number of times MH4 is detected within a four-minute period at hourly intervals. The device determines the MH4 biomarker counts at each hourly collection point and the data are stored on the device. Under normal conditions, transformations of the data are visualized on the display. For this clinical trial, the display is obscured. Therefore, no value will be displayed for interpretation since this is a non-intervention trial and the device is not intended to affect or influence the standard of care for study participants.
