Summary

The purpose and aim of this study are to compare changes in pulse volume to non-invasively predict active bleeding or high-risk stigmata in patients undergoing a gastrointestinal endoscopy to assess feasibility of the flow meter clinically.

Detailed description

The maximum change in volume of a limb segment during the cardiac cycle - pulse volume - will be monitored non-invasively along with standard vitals in patients with a suspected gastrointestinal bleed undergoing endoscopy. Pulse volume and vitals will be collected prior to and following endoscopy up to the point of dismissal from the endoscopy unit so that the data may be correlated with the endoscopic and clinical findings.

Conditions

• GastroIntestinal Bleeding

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Pulse flowmeter	Measures peripheral pulse volumes by an electrode applied non-invasively to the lower extremity (left or right) at the beginning of the endoscopic evaluation for the duration of the procedure, and up to 2 hours after the completion of the procedure.
