Study of the Influence of Various Stress-Based Mechanisms on Polarization of an SM mPOF for the Development of Useful Devices
(IEEE, 2017-07-15)
In contrast to conventional polymer optical fibres (POFs), single-mode microstructured POFs (SM mPOF) exhibit polarization properties that make them potentially interesting for their use in the design and development of ...
Accurate Strain Sensing Based On Super-Mode Interference In Strongly Coupled Multi-Core Optical Fibres
(Nature Publishing Group, 2017-06-30)
We report on the use of a multi-core fibre (MCF) comprising strongly-coupled cores for accurate strain sensing. Our MCF is designed to mode match a standard single mode optical fibre. This allows us to fabricate simple MCF ...
Design, Fabrication and Testing of a High-Sensitive Fibre Sensor for Tip Clearance Measurements
(MDPI, 2018-08)
A highly sensitive fibre bundle-based reflective optical sensor has been designed and fabricated for Tip Clearance measurements in a turbine rig. The sensor offers high spatial and temporal resolution. The sensor probe ...
Pulseless electrical activity in in-hospital cardiac arrest - A crossroad for decisions
(Elsevier, 2022-07)
Background
PEA is often seen during resuscitation, either as the presenting clinical state in cardiac arrest or as a secondary rhythm following transient return of spontaneous circulation (ROSC), ventricular ...
Monitoring Chest Compression Quality During Cardiopulmonary Resuscitation: Proof-Of-Concept Of A Single Accelerometer-Based Feedback Algorithm
(Public Library Science, 2018-02-14)
Background
The use of real-time feedback systems to guide rescuers during cardiopulmonary resuscitation (CPR) significantly contributes to improve adherence to published resuscitation guidelines. Recently, we designed ...
U-Shaped and Surface Functionalized Polymer Optical Fiber Probe for Glucose Detection
(MDPI, 2017-01)
In this work we show an optical fiber evanescent wave absorption probe for glucose detection in different physiological media. High selectivity is achieved by functionalizing the surface of an only-core poly(methyl ...
Modeling the impact of ventilations on the capnogram in out-of-hospital cardiac arrest
(Public Library Science, 2020-02-05)
Aim
Current resuscitation guidelines recommend waveform capnography as an indirect indicator of perfusion during cardiopulmonary resuscitation (CPR). Chest compressions (CCs) and ventilations during CPR have opposing ...
Enhancing ventilation detection during cardiopulmonary resuscitation by filtering chest compression artifact from the capnography waveform
(Public Library Science, 2018-08-02)
Background
During cardiopulmonary resuscitation (CPR), there is a high incidence of capnograms distorted by chest compression artifact. This phenomenon adversely affects the reliability of automated ventilation detection ...
A New Method for Feedback on the Quality of Chest Compressions during Cardiopulmonary Resuscitation
(Hindawi Publishing, 2014)
Quality of cardiopulmonary resuscitation (CPR) improves through the use of CPR feedback devices. Most feedback devices integrate the acceleration twice to estimate compression depth. However, they use additional sensors ...
Feedback on the Rate and Depth of Chest Compressions during Cardiopulmonary Resuscitation Using Only Accelerometers
(Public Library Science, 2016-03-01)
Background
Quality of cardiopulmonary resuscitation (CPR) is key to increase survival from cardiac arrest. Providing chest compressions with adequate rate and depth is difficult even for well-trained rescuers. The use ...
