Methods and apparatus are provided for assessing endothelial function in a mammal. The methods involve applying to the artery a substantially constant external pressure, where the pressure is provided via a cuff adjacent to and/or around a region of the mammal's body; determining, over the ...

Cuffless blood pressure (BP) measurement is an all-inclusive term for a method that aims to measure BP without using a cuff. Recent cuffless technology has made it possible to estimate BP with reasonable accuracy. However, mainstream methods require
An elastic inflatable cuff (1) and two measuring devices (5,11) are arranged next to an artery (2). In the measurement cycle, the cuff is inflated until the pulse is no longer detected by the measuring device (5), and the pressure in the cuff is gradually reduced. The cuff pressure ...
Pulse Transit Time Based Continuous Cuffless Blood Pressure Estimation: A New Extension and A Comprehensive Evaluation Cuffless technique enables continuous blood pressure (BP) measurement in an unobtrusive manner, and thus has the potential to revolutionize the conventional cuff-based approaches. This st...
Arrangement for controlling the cuff pressure in the indirect, non- invasive, continuous measurement of blood pressure in a finger by using a photo-electric plethysmograph in a fluid-filled pressure cuff, an electronic control circuit an... KH Wesseling,Benjamino de Wit - EP 被引量: 56发表:...
A blood pressure meter using a viscoelastic cuff and a mobile terminal having the same are provided to decrease a size of the blood pressure meter by measuring a blood pressure with the viscoelastic cuff instead of an air pressure cuff. A pressure adjusting unit includes a cuff(200a) that is...
In this work, we propose a feature exploration method for learning-based cuffless blood pressure measurement. More specifically, to efficiently explore a large feature space from the photoplethysmography signal, we have applied several analytical techniques, including random error elimination, adaptive outl...
Blood pressure is a significant vital sign; blood pressure monitoring has a great significance to determine the health status of patients. In this project blood pressure, Temperature and heart beat are estimated by using sensors and the result is viewed in smart phones by using GSM and if any ...
For each pressure reading, the cuff needs to be inflated and deflated, which approximately consumes 1 to 2 min of time between two successive readings [9]. As a result of these short-term changes, pressure cannot be monitored accurately; for instance, the inflation of the cuff itself might ...
