A New Design of Pain Monitoring System during General Anesthesia Operations Based on Pulse Wave Transfer Function

Article Preview

Abstract:

Pain monitoring is essential during general anesthesia operations. Previous researchers have found relationship between pulse wave and painful stimulation and introduced parameters based on photoplethysmography (PPG). According to arterial windkessel model, pulse wave transfer function (PWTF) would represent the transmission of stimulation but there was little research on this. A synchronous dual channel PPG acquiring system with ECG circuit and external blood pressure module is built to push on the research. System works well with testers aged from 10 to 65, both male and female.
