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 ...
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 ...
Assessment of the Evolution of End-Tidal Carbon Dioxide within Chest Compression Pauses to Detect Restoration of Spontaneous Circulation
(Public Library Of Science, 2021-05-18)
Background
Measurement of end-tidal CO2 (ETCO2) can help to monitor circulation during cardiopulmonary resuscitation (CPR). However, early detection of restoration of spontaneous circulation
(ROSC) during CPR using ...
Experimental Study of the Summation of Flicker Caused by Wind Turbines
(MDPI, 2019-06-22)
Integration of wind energy into the grid faces a great challenge regarding power quality. The International Electrotechnical Commission (IEC) 61400-21 standard defines the electrical characteristics that need to be assessed ...
Flicker of Modern Lighting Technologies Due to Rapid Voltage Changes
(MDPI, 2019-03-01)
The purpose of the present paper is to evaluate the sensitivity of modern lighting technologies to different types of RVCs. In order to do that, 27 modern lampsmainly LEDhave been subjected to real RVCs and their response ...
Monitoring Chest Compression Rate in Automated External Defibrillators Using the Autocorrelation of the Transthoracic Impedance
(Public Library Science, 2020-09-30)
Aim High-quality chest compressions is challenging for bystanders and first responders to out-of-hospital cardiac arrest (OHCA). Long compression pauses and compression rates higher than recommended are common and detrimental ...
Experimental Study of the Response of Efficient Lighting Technologies to Complex Voltage Fluctuations
(Elsevier, 2014-07-09)
The replacement of incandescent lamps with more energy-efficient lighting technologies has a direct influence on the way flicker is measured. The International Electrotechnical Commission (IEC) established in the 61000-4-15 ...
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 ...
