SmartPill Intestinal Transit
Description
This dataset, intestinal_smartpill_df, is a data frame from a prospective cohort study evaluating gastric emptying, small bowel transit time, and total intestinal transit time using a SmartPill motility capsule. The study involved 8 critically ill trauma patients and 87 healthy volunteers. The capsule wirelessly transmitted pH, pressure, and temperature to a recorder attached to each subject's abdomen.
