摘要
Abstract
Objective To investigate the feasibility of stress assessment based on specific quantification techniques and analysis of stress status with photoplethysmographic (PPG) signals. Methods The PPG signals were stratified and randomly sampled from 58 recruits before and after stress induced by International Affective Pictures Systems (LAPS) images of negative emotion. The signals were collected and processed in a tool called HC2180-D, an enhanced solution of a blood flow monitoring system, through which the characteristic parameters of pulsatile waveform were derived as components of bioinformation for quantitative and comparative study. A concise mental rating scale, the "brief profile of mood state" (BPOMS), was used as criterion. Results As the characteristic parameter and biomarker were derived, significant increases in values were observed in both the vasoconstriction/vasodilation fraction (CDF) and the ordinate of the area under the pulse contour of the vasoconstriction phase (Y2) when the recruits were shown LAPS images of negative emotion ( P<0.05),compared with the resulting values when I APS images of neutral emotion (P>0.05) were shown. The values of both the CDF and the Y2 were positively correlated in mid-range to tension, depression, and anger (P<0.05), and in low-range to fatigue and confusion ( P<0.05). The values were negatively correlated in mid-range with vigor ( P<0.05). Conclusion The characteristic parameter and biomarker derived from the pulsatile waveform obtained at the fingertip are highly sensitive and can be utilized as measures in the quantitative assessment of stress response among recruits.关键词
