Estimation of Mental Distress from Photoplethysmography
This paper introduces the design of a new wearable photoplethysmography (PPG) sensor and its assessment for mental distress estimation. In our design, a PPG sensor obtains blood volume information by means of an optical plethysmogram technique. A number of temporal, morphological and frequency markers are computed using time intervals between adjacent normal cardiac cycles to characterize pulse...
متن کاملEffects of noise annoyance on mental distress
Introduction: Noise is one of the most harmful physical factors in the workplace that can cause annoyance. Therefore, the aim of this study was to investigate the effect of annoyance caused by occupational noise on employee’s mental distress. Materials and Methods: This analytical-descriptive study was performed on 325 employees of the parts manufacturing industry in seven groups and the noise ...
متن کاملRespiration signals from photoplethysmography.
Pulse oximetry is based on the technique of photoplethysmography (PPG) wherein light transmitted through tissues is modulated by the pulse. In addition to variations in light modulation by the cardiac cycle, the PPG signal contains a respiratory modulation and variations associated with changing tissue blood volume of other origins. Cardiovascular, respiratory, and neural fluctuations in the PP...
متن کاملEstimation of biophysical and functional properties of artery walls from pulse wave measured by photoplethysmography
Arterial pulse wave analysis in time and frequency domain was carried out to find out biophysical and functional properties of artery walls measured with a photoplethysmographic (PPG) device. Because peripheral arterial disease (PAD) is a fatal problem all over the world, an easy diagnosis method would be needed. It could probably be diagnosed by PPG which is a non-invasive optical technique fo...
متن کاملDomestic Violence and Mental Distress
The article highlights the traumatic impact of intimate partner domestic violence (IPDV) on women, the complexity of their responses to it, its impact on their identities, and their resulting social position in Europe. An exploration of the intersectionalities between IPDV and mental distress within the context of negative social attitudes toward IPDV victims follows, highlighting the psychosoc...
