A Machine Learning Model for the Prognosis of Pulseless Electrical Activity during Out-of-Hospital Cardiac Arrest
(MDPI, 2021-06-30)
Pulseless electrical activity (PEA) is characterized by the disassociation of the mechanical and electrical activity of the heart and appears as the initial rhythm in 20–30% of out-of-hospital cardiac arrest (OHCA) cases. ...
Rhythm Analysis during Cardiopulmonary Resuscitation Using Convolutional Neural Networks
(MDPI, 2020-05-27)
Chest compressions during cardiopulmonary resuscitation (CPR) induce artifacts in the ECG that may provoque inaccurate rhythm classification by the algorithm of the defibrillator. The objective of this study was to design ...
Packaged multi-core fiber interferometer for high temperature sensing
(IEEE, 2019-03-07)
[EN]A small size and compactly packaged optical sensor for high-temperature measurements is reported. The sensor consists of a short piece of multi-core fiber (MCF) spliced to the distal end of a single-mode fiber. The ...
Flicker Characteristics of Efficient Lighting Assessed by the IEC Flickermeter
(Elsevier, 2013-10-13)
We present an experimental study of the behavior of modern lighting technologies
under supply voltage fluctuations. Some studies have reported that flicker severity
measurements could exceed the compatibility levels ...
An Alternative Strategy to Improve the Flicker Severity Measurement
(Elservier, 2014-07-12)
The IEC 61000-4-15 standard defines a flickermeter that is universally accepted as the meter used for the objective measurement of a disturbing light flicker. The accurate results provided by the IEC flickermeter under ...
Deep Neural Networks for ECG-Based Pulse Detection during Out-of-Hospital Cardiac Arrest
(MDPI, 2019-03-21)
The automatic detection of pulse during out-of-hospital cardiac arrest (OHCA) is necessary for the early recognition of the arrest and the detection of return of spontaneous circulation (end of the arrest). The only signal ...
Liquid-Core Microstructured Polymer Optical Fiber as Fiber-Enhanced Raman Spectroscopy Probe for Glucose Sensing
(IEEE, 2019-07)
[EN] This work reports the development and application
of two liquid-core microstructured polymer optical fibers (LCmPOF)
with different microstructure sizes. They are used in a
fiber-enhanced Raman spectroscopy sensing ...
A Machine Learning Framework for Pulse Detection During Out-of-Hospital Cardiac Arrest
(IEEE, 2020-09-02)
The availability of an automatic pulse detection during out-of-hospital cardiac arrest (OHCA)
would allow the rapid identi cation of cardiac arrest and the prompt detection of return of spontaneous
circulation. The aim ...
A Multistage Algorithm for ECG Rhythm Analysis During Piston-Driven Mechanical Chest Compressions
(IEEE, 2019-01)
Goal: An accurate rhythm analysis during cardiopulmonary resuscitation (CPR) would contribute to increase the survival from out-of-hospital cardiac arrest. Piston-driven mechanical compression devices are frequently used ...
A Machine Learning Shock Decision Algorithm for Use During Piston-Driven Chest Compressions
(IEEE, 2019-06)
Goal: Accurate shock decision methods during piston-driven cardiopulmonary resuscitation (CPR) would contribute to improve therapy and increase cardiac arrest survival rates. The best current methods are computationally ...
