A Web Application for Experimenting and Validating Remote Measurement of Vital Signs
TL;DR: A web application framework to measure a person’s Heart Rate, Heart Rate Variability, Oxygen Saturation, Respiration Rate, Blood Pressure, and stress from the face video using Remote Photoplethysmography techniques that compute vital signs from facial videos.
Journal ArticleDOI
Photoplethysmography based instant remote monitoring of non-invasive blood pressure and oxygen saturation by using zigbee network
TL;DR: It is proposed that measuring and transmitting these vital signals through a wireless network enables/ provides authorized staff to observe them remotely for instant intervention and doesn’t discomfort the patient since the method’s non-invasive photoplethysmography technique.
Proceedings ArticleDOI
A novel signal processing method for the measurement of venous refilling time
TL;DR: Test results obtained from a prototype unit, built under the LabVIEW virtual environment, establish the validity of the model and the proposed signal processing technique for the measurement of VRT.
Journal ArticleDOI
Prospective validation of smartphone-based heart rate and respiratory rate measurement algorithms
TL;DR: In this article , the authors evaluated smartphone camera-based techniques for measuring heart rate (HR) and respiratory rate (RR) for consumer wellness use, and the results validated the accuracy of their smartphone camerabased techniques to measure HR and RR across a range of pre-defined subgroups.
