Photoplethysmographic Dichrotic Notch Reflexes Systemic Hemodynamics

NCT04179097 · Status: TERMINATED · Type: OBSERVATIONAL · Enrollment: 15

No results posted yet for this study

Summary

Changes in the vascular tone of anesthetized patients is common and cause hemodynamic problems. The investigators have previously demonstrated that the shape of the pulse oximetry waveform (photoplethysmography) is closely related to the changes observed in systemic vascular resistence. The main change in pulse waveform is based to the dichrotic notch position. The present study was designed to determine if the dichrotic notch position is related to a local or a systemic change in the vascular tone.
