SOLUTION: The cuff band of the blood pressure meter has upper layer pressure air bags 6A and 6B, which have an air supply and exhaust connection port 9 for supplying and exhausting compressed air, and a lower layer measuring air bag 7, which is allowed to communicate with the pressure air...
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 (PTT) is a potential parameter for cuffless blood pressure (BP) estimation. Since exercise induces changes in arterial properties that c... YM Wong,E Pickwell-Macpherson,YT Zhang - 《European Journal of Applied Physiology》 被引量: 52发表: 2009年 Photoplethysmogram intensity...
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
In all cases, an occlusive cuff is used as an external pressure source. The major disadvantage of using such cuff-based BP monitors is that they cannot be used for continuous monitoring. Cuff-based BP monitors also suffer from inaccuracies due to incorrect placement of the cuff [8].These ...

Overriding the baroreceptive information of afferent nerve fibers, originating from pressure sensors in the aortic arch, can trigger the baroreflex, a systemic control system that lowers the blood pressure (BP) almost instantaneously. Using a multichannel cuff electrode, wrapped around a rat vagal ...
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...
Catheterization is a medical procedure in which a thin, flexible tube called a catheter is inserted into a blood vessel to diagnose and treat heart conditions. Angiography is a medical imaging technique that uses X-rays and a contrast agent to visualize the blood vessels inside the body. Both ...
With the Finapres the signals are obtained using a finger cuff and an upper arm cuff for calibration of the reconstructed blood pressure. Although cardiovascular signals are sampled continuously by the Finometer, calculations for a number of relevant measures are performed for each heartbeat n, ...
