Channel phase processing in wireless networks for human activity recognition
(Elsevier, 2023-12)
The phase of the channel state information (CSI) is underutilized as a source of information in wireless sensing due to its sensitivity to synchronization errors of the signal reception. A linear transformation of the phase ...
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 ...
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 ...
Restoration of the electrocardiogram during mechanical cardiopulmonary resuscitation
(IOP, 2020-04-04)
Objective: An artefact-free electrocardiogram (ECG) is essential during cardiac arrest to decide therapy such as defibrillation. Mechanical cardiopulmonary resuscitation (CPR) devices cause movement artefacts that alter ...
The Role of Chest Compressions on Ventilation during Advanced Cardiopulmonary Resuscitation
(MDPI, 2023-11-03)
There is growing interest in the quality of manual ventilation during cardiopulmonary resuscitation (CPR), but accurate assessment of ventilation parameters remains a challenge. Waveform capnography is currently the reference ...
Characterization of mechanical properties of adult chests during pre-hospital manual chest compressions through a simple viscoelastic model
(Elsevier, 2023-12)
Aim
The purpose of this study was to develop a simple viscoelastic model to characterize the mechanical properties of chests during manual chest compressions in pre-hospital cardiopulmonary resuscitation (CPR).
Metho ...
Optical fiber interferometer for temperature-independent refractive index measuring over a broad range
(Elsevier, 2021-07)
The present work relates to manufacturing of a simple interferometric optical fiber refractometer that features broad refractive index measuring range without ambiguity. The device consists of a cylindrical polymer cavity ...
