  • First Steps Toward Automated Classification of Impedance Cardiography dZ/dt Complex Subtypes

    • The detection of the characteristic points of the complex of the impedance cardiography (ICG) is a crucial step for the calculation of hemodynamical parameters such as left ventricular ejection time, stroke volume and cardiac output. Extracting the characteristic points from the dZ/dt ICG signal is usually affected by the variability of the ICG complex and assembling average is the method of choice to smooth out such variability. To avoid the use of assembling average that might filter out information relevant for the hemodynamic assessment requires extracting the characteristics points from the different subtypes of the ICG complex. Thus, as a first step to automatize the extraction parameters, the aim of this work is to detect automatically the kind of dZ/dt complex present in the ICG signal. To do so artificial neural networks have been designed with two different configurations for pattern matching (PRANN) and tested to identify the 6 different ICG complex subtypes. One of the configurations implements a 6-classes classifier and the other implemented the divide and conquer approach classifying in two stages. The data sets used in the training, validation and testing process of the PRANNs includes a matrix of 1 s windows of the ICG complexes from the 60 s long recordings of dZ/dt signal for each of the 4 healthy male volunteers. A total of 240 s. As a result, the divide and conquer approach improve the overall classification obtained with the one stage approach on +26% reaching and average classification ration of 82%.

  • Evaluation of dZ/dt Complex Subtypes vs Ensemble Averaging Method for Estimation of Left Ventricular Ejection Time from ICG Recording
  • 2021
  • Ingår i: 8th European Medical and Biological Engineering ConferenceProceedings of the EMBEC 2020, November 29 – December 3, 2020 Portorož, Slovenia. - Cham : Springer Science and Business Media Deutschland GmbH. - 9783030646097 - 9783030646103 ; , s. 502-509

    • Impedance cardiography (ICG) was discovered nearly half a century ago, being proposed as noninvasive monitoring method for estimation of several hemodynamics parameter. Despite of nearly 5 decades of clinical research and use there is still certain controversy about its performance when estimating Left Ventricular Ejection Time (LVET). This work present a comparison between using the different ICG subtype waveform and the ensemble averaged (EA) method to calculate the LVET. The ICG has been recorded from four volunteers, and the LVET parameter has been calculated using the two approaches. The result shows that each volunteer have different percentage of subtypes, and the mean relative error between the two approaches for estimation of LVET varied between 0.62 to 2.9% with an average mean absolute percentage error of 18,02% ranging between 13.82 to 18.42%. © 2021, Springer Nature Switzerland AG.

  • [WORKSHOP] Designerly ways of engaging with nature
  • 2023
  • Ingår i: 26th International Academic Mindtrek Conference. - Tampere Finland : ACM Press. - 9798400708749 ; , s. 309-312
  • Konferensbidrag (refereegranskat)abstract
    • In this workshop, we will bring together designers and researchers working with, for, and around nature to facilitate a transversal conversation around how to engage nature as a key part of our design processes. By deliberately adopting an open and ambiguous idea of what we mean by ‘nature’, we hope to embrace diverse kinds of more-than-human entanglements, including (but not only): farming, companion species, microbiomes, body ecologies, forests and other large-scale landscapes (e.g. oceans), or cohabitation in houses. We argue for the importance of taking such an open-ended perspective, to embrace all possible relevant vectors of nature-related design: multispecies, cohabitation, posthuman sustainability, posthuman care… The workshop is set as a as a platform for shared methodological reflection through the lenses of a more-than-human approach to posthuman research. It will primarily be in-person, given our aim of bringing researchers together and co-experiencing each others’ methods and techniques.
