Time-Series U-Net With Recurrence for Noise-Robust Imaging Photoplethysmography

IEEE Access
Remote estimation of vital signs enables health monitoring for situations in which contact-based devices are either not available, too intrusive, or too expensive. In this paper, we present a modular pipeline for pulse signal estimation from video of the

Wireless monitoring of liver hemodynamics in vivo [PDF]

, 2014
Liver transplants have their highest technical failure rate in the first two weeks following surgery. Currently, there are limited devices for continuous, real-time monitoring of the graft.

Psychophysiological indicators of emotional arousal in sexual assault survivors: Evaluating ANS reactivity to therapeutic COPE cards within the SEE FAR CBT framework for PTSD treatment

Psychology and Psychotherapy: Theory, Research and Practice, EarlyView.
Abstract Objective SEE FAR CBT is an integrative treatment protocol for PTSD and anxiety disorders, utilizing imagery‐based (fantastic reality) methods through associative therapeutic COPE cards. Although preliminary evidence suggests potential impacts, further validation is necessary to confirm their efficacy in eliciting specific arousal‐affective ...

Heart rate monitoring in ultra-high-field MRI using frequency information obtained from video signals of the human skin compared to electrocardiography and pulse oximetry

Current Directions in Biomedical Engineering, 2015
Videos of the human skin contain subtle color variations associated with the blood volume pulse. This remote photoplethysmography signal can be used for heart rate monitoring and represents an alternative to signals obtained from contact-based hardware ...

Cerebral haemodynamic responses to inspiratory muscle work

Experimental Physiology, EarlyView.
Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

Influence of a neck compression collar on cerebrovascular and autonomic function in men and women [PDF]

, 2019
Objective Neck compression collars have been proposed to reduce injury to the brain caused by head impacts. Our objective was to test if compression of the carotid artery affected the baroreflex and influenced blood pressure control.

Whole‐body hot water immersion effect on cerebral haemodynamics and subsequent cerebrovascular reactivity to carbon dioxide

Experimental Physiology, EarlyView.
Abstract To test the hypothesis that hot water immersion (HWI) improves cerebrovascular function via shear‐mediated mechanisms, this study determined cerebrovascular reactivity to carbon dioxide (CVRCO2${\mathrm{CV}}{{\mathrm{R}}_{{\mathrm{C}}{{\mathrm{O}}_2}}}$) before and after 60 min of 39°C HWI and a 21°C air control (CON) in 15 healthy ...
