Non-invasive continuous blood pressure monitoring: a review of current applications

Elena Chung, Guo Chen, Brenton Alexander, Maxime Cannesson

Frontiers of Medicine 2013, Volume 7, Issue 1, Pages 91-101 doi: 10.1007/s11684-013-0239-5

Abstract:

Blood pressure monitoring has come a long way from the initial observations made by Reverend Hales in the 18th century. There are none that deny the importance of monitoring perioperative blood pressure; however, the limited ability of the current prevalent technology (oscillometric blood pressure monitoring) to offer continuous blood pressure measurements leaves room for improvement. Invasive monitoring is able to detect beat-to-beat blood pressure measurement, but the risks inherent to the procedure make it unsuitable for routine use except when this risk is outweighed by the benefits. This review focuses on the discoveries which have led up to the current blood pressure monitoring technologies, and especially the creation of those offering non-invasive but continuous blood pressure monitoring capabilities, including their methods of measurement and limitations.

Dynamic analysis of rail transit elevated bridge with ladder track

He XIA, Yushu DENG, Yongwei ZOU, Guido DE ROECK, Geert DEGRANDE

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 1, Pages 2-8 doi: 10.1007/s11709-009-0001-x

Abstract: In this paper, a dynamic analysis model of an elevated bridge with ladder tracks under moving train load is established. The whole process of a train running through an elevated bridge at different speeds is simulated. The dynamic responses of the elevated bridge with ladder track and the running safety and comfort index of train vehicles are evaluated. Compared with the dynamic responses of an elevated bridge with ordinary non-ballasted slab track, the ladder track’s effect on reducing the vibration of an elevated bridge is analyzed. The analysis results show that the ladder track has good vibration reduction characteristics as compared to ordinary non-ballasted track.
