Objective: Today, there are various non-invasive techniques available for the determination of blood glucose levels. In this study, the level of blood glucose was determined by developing a new device using near-infrared (NIR) wavelength, glass optical waveguide, and the phenomenon of evanescent waves. Materials and Methods: The body's interstitial fluid has made possible the development of ne...

BACKGROUND We compared Nexfin non-invasive arterial pressure measurements using a novel small finger cuff with intra-arterial pressure in the paediatric setting in order to establish the level of agreement between both methods. METHODS The study included 41 children aged 2-16 yr admitted for surgery or paediatric intensive care with an intra-arterial catheter as part of standard monitoring. V...

Nowadays most of the blood pressure measuring devices rely on a common concept of inflatable cuff to the arm which is based on auscultatory or oscillometry principle. These existing blood pressure meters, based on cuff are considered to be inconvenient for daily monitoring and these are very sensitive to artefacts due to the presence of cuff. The other non invasive methods like PTT, PAT require...

Photoplethysmography is a non-invasive electro-optical technique widely used in the study and monitoring of the pulsations associated with changes in blood volume in a peripheral vascular bed. Photoplethysmography is used in the estimation of arterial oxygen saturation (SpO2) by pulse oximetry. A reflectance finger photoplethysmographic (PPG) probe and a multiplexed data acquisition system oper...

The periodic and frequent measurements of blood pressure for hypertensive patients are must to do their effective and efficient monitoring. Existing non-invasive blood pressure measurement instruments mandate a relaxed posture – it is considered a prerequisite to factor out motion artifacts in the reading – before taking the final reading. This requirement causes not only a great discomfort for...

Blood pressure monitoring is essential in managing hemodynamically unstable neonates and preterm infants. Non-invasive blood pressure measurement (NIBP) with oscillometric technique is in widespread use in the Neonatal Intensive Care Units (NICUs). Nonetheless NIBP is not pretty accurate when compared with invasive monitoring since it generally over read mean blood pressure in particular when t...

In recent years, Pulse Transit Time (PTT) based non-invasive continuous blood pressure monitoring systems have been investigated extensively. But the most relevant studies did not pay attention to the safety requirement of the system. In this paper a method is proposed to model the safety-related system for continuous noninvasive blood pressure monitoring. The hardware, software and communicati...

The purpose of the article is to describe possible ways of non-invasive measuring and analysis of blood circulation parameters. These parameters are very important indicators of various cardiovascular diseases in clinical practice. For this purpose, methods of purely non-invasive analysis are sought. A standard approach is to use an inflatable cuff for blood pressure monitoring and analysis, us...
