Pulse Photoplethysmographic Analysis Estimates the Sympathetic Activity Directed to Heart and Vessels.


BACKGROUND Novel pulse photoplethysmographic-derived indices have been proposed as tools to measure autonomic nervous system (ANS) modulation in anesthetized and awake patients, but nowadays their experimental validation is lacking. The authors aimed to investigate the ability of pulse photoplethysmographic amplitude (PPGA), ANS state (ANSS), and ANSS index… (More)
