Estimation of Autonomic Nervous System Modulation by Pulse Plethysmographic Analysis
In Brief
A clinical study evaluating Tilt test for Autonomic Nervous System Modulation. Completed, enrolled 10 participants across 1 site.
Detailed Summary
Novel pulse plethysmography-derived indexes has been proposed as a tool to measure autonomic nervous system modulation in anaesthetized and awake patients, but nowadays a physiologic validation is lacking. We aim to examine the effects of sympathetic stimulation on pulse plethysmographic amplitude (PPGA), autonomic nervous system state (ANSS) and autonomic nervous system state index (ANSSi).
Study Details
Timeline
Interventions
The experiment protocol consists of a sequence of passive postural changes gained with a tilt table, each of them lasting 10 minutes. The sequence consists of: (i) baseline recording in supine position; (ii) tilt at 45 degrees angle; (iii) recovery period in supine position; (iv) tilt at 90 degrees angle and (v) recovery in supine position.
