Photoplethysmography for Diagnose Incipient Hypovolemia

NCT05512611 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 60

No results posted yet for this study

Summary

Hypovolemia caused by acute bleeding increased morbi-mortality in emergency and operatin rooms. Precise real-time diagnosis of incipient acute hypovolemia is lacking at the bedside. We hypothesize that the infrared-red signals of pulse oximetry are sensitive to acute changes in patient's volemia. We aimed to test this hypothesis in a cohort of healthy blood donors as a model of simulated acute hypovolemia.
