A New Method to Design Trifurcated Optical Fiber Displacement Sensors
(IEEE, 2024-01)
Trifurcated optical fiber displacement sensors (OFDSs) are increasingly used in industrial and aerospace applications. The critical element of the sensor is the fiber bundle. However, there is no straightforward method to ...
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 ...
Cardiac output estimation using ballistocardiography: a feasibility study in healthy subjects
(Nature, 2024)
There is no reliable automated non-invasive solution for monitoring circulation and guiding treatment in prehospital emergency medicine. Cardiac output (CO) monitoring might provide a solution, but CO monitors are not ...
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 ...
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 ...
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 ...
Contribution of chest compressions to end-tidal carbon dioxide levels generated during out-of-hospital cardiopulmonary resuscitation
(Elsevier, 2022-10)
Aim
Characterise how changes in chest compression depth and rate affect variations in end-tidal CO2 (ETCO2) during manual cardiopulmonary resuscitation (CPR) in out-of-hospital cardiac arrest (OHCA).
Methods
Retrospective ...
Review of a Custom-Designed Optical Sensing System for Aero-Engine Applications
(MDPI, 2021-02-25)
Fibre bundle-based reflective optical sensors are good candidates for parameter monitorisation in aero engines. Tip clearance is one of those parameters of great concern that is necessary to monitor. Within this optical ...
