Acute Gastrointestinal Bleeding Peripheral Pulse Volume Changes
- Conditions
- GastroIntestinal Bleeding
- Registration Number
- NCT06441201
- Lead Sponsor
- Mayo Clinic
- Brief 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.
