Remote plethysmographic imaging using ambient light
TL;DR: Plethysmographic signals were measured remotely (>1m) using ambient light and a simple consumer level digital camera in movie mode as discussed by the authors, which may be useful for medical purposes such as characterization of vascular skin lesions and remote sensing of vital signs (e.g., heart and respiration rates) for triage or sports purposes.
Journal ArticleDOI
Toward Ubiquitous Blood Pressure Monitoring via Pulse Transit Time: Theory and Practice.
Ramakrishna Mukkamala,Jin-Oh Hahn,Omer T. Inan,Lalit Keshav Mestha,Chang-Sei Kim,Hakan Toreyin,Survi Kyal +6 more
TL;DR: This review explains the conventional BP measurement methods and their limitations; presents models to summarize the theory of the PTT-BP relationship; outlines the approach while pinpointing the key challenges; and discusses realistic expectations for the approach.
Journal ArticleDOI
Photoplethysmography Revisited: From Contact to Noncontact, From Point to Imaging
Yu Sun,Nitish V. Thakor +1 more
TL;DR: This study presents an overview of the wide range of IPPG systems currently being introduced along with examples of their application in various physiological assessments and believes that the widespread acceptance ofIPPG is happening, and it will dramatically accelerate the promotion of this healthcare model in the near future.
Journal ArticleDOI
Photoplethysmography pulse rate variability as a surrogate measurement of heart rate variability during non-stationary conditions
Eduardo Gil,Michele Orini,Michele Orini,Raquel Bailon,Jose Maria Vergara,Luca Mainardi,Pablo Laguna +6 more
TL;DR: Although some differences in the time-varying spectral indices extracted from HRV and PRV exist, mainly in the HF band associated with respiration, PRV could be used as a surrogate of HRV during non-stationary conditions, at least during the tilt table test.
Journal ArticleDOI
Improvements in Remote Cardiopulmonary Measurement Using a Five Band Digital Camera
TL;DR: Results of PPG measurements from a novel five band camera are presented and it is shown that alternate frequency bands, in particular an orange band, allowed physiological measurements much more highly correlated with an FDA approved contact PPG sensor.
