Effect of the sampling rate on the assessment of flicker severity due to phase jumps
(IEEE, 2011)
This paper presents an analysis of the effect of the sampling rate on the calculation by a digital flickermeter of the flicker severity caused by phase jumps. The new edition of the IEC 61000-4-15 standard includes an ...
Influence of carrier phase on flicker measurement for rectangular voltage fluctuations
(IEEE, 2011-11-01)
This paper presents an analysis of the influence of the phase relationship between the fundamental frequency and the rectangular voltage fluctuation on flicker measurements made by the International Electrotechnical ...
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 ...
Measurement Methodology for Determining the Optimal Frequency Domain Configuration to Accurately Record WiFi Exposure Levels
(IEEE, 2018-07-04)
[EN] Radiofrequency fields are usually measured in order to be compared with electromagnetic exposure limits defined by international standardization organizations with the aim of preserving the human health. However, in ...
Evaluation of chest compression artefact removal based on rhythm assessments made by clinicians
(Elsevier, 2018-01-31)
Aim
To evaluate the performance of a state-of-the-art cardiopulmonary resuscitation (CPR) artefact suppression method by assessing to what extent the filtered electrocardiogram (ECG) can be correctly diagnosed by emergency ...
Threats and Limitations of Terrestrial Broadcast Attacks
(IEEE, 2018-03)
[EN] The DVB standard does not mandate the use of authentication and integrity protection for transport streams. This allows malicious third parties to replace legitimate broadcasts by overpowering terrestrial transmissions. ...
Spanish vs USA cohort comparison of prehospital trauma scores to predict short-term mortality
(Elsevier, 2024-05)
Background
This study aimed to evaluate three prehospital early warning scores (EWSs): RTS, MGAP and MREMS, to predict short-term mortality in acute life-threatening trauma and injury/illness by comparing United States ...
Metrics of impulsiveness of manual chest compressions for out-of-hospital cardiopulmonary resuscitation
(Elsevier, 2024-04)
Aim
Propose new metrics of impulsiveness of manual chest compressions (CCs) that account for shape and duration, separate the characteristics of the compressive part of the CC cycle from those of the recoil part, and ...
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 ...
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 ...
