  • Hypoxia-induced effects on ECG depolarization by time warping analysis during recurrent obstructive apnea 

    Romero Pérez, Daniel; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    this work, we evaluated a non-linear approach to estimate morphological variations in ECG depolarization, in the context of intermittent hypoxia (IH). Obstructive apnea sequences were provoked for 15 minutes in anesthetized ...
  • Cardiovascular coupling-based classification of ischemic and dilated cardiomyopathy patients 

    Rodríguez Benítez, Javier; Schulz, Steffen; Voss, Andreas; Giraldo Giraldo, Beatriz (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    Cardiovascular diseases are one of the most common causes of death in elderly patients. The etiology of cardiomyopathies is difficult to discern clinically. The objective of this study was to classify cardiomyopathy patients ...
  • Linear mixed effects modelling of oxygen desaturation after sleep apneas and hypopneas: a pilot study 

    Solà Soler, Jordi; Giraldo Giraldo, Beatriz; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Restricted access - publisher's policy
    Obstructive Sleep Apnea severity is commonly determined after a sleep polysomnographic study by the Apnea-Hypopnea Index (AHI). This index does not contain information about the duration of events, and weights apneas and ...
  • Neural offset time evaluation in surface respiratory signals during controlled respiration 

    Estrada Petrocelli, Luis Carlos; Sarlabous, Leonardo; Lozano García, Manuel; Jané Campos, Raimon; Torres Cebrián, Abel (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Restricted access - publisher's policy
    The electrical activity of the diaphragm measured by surface electromyography (sEMGdi) provides indirect information on neural respiratory drive. Moreover, it allows evaluating the ventilatory pattern from the onset and ...
  • Analysis of tracheal and pulmonary continuous adventitious respiratory sounds in asthma 

    Lozano García, Manuel; M. Davidson, Clare; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Restricted access - publisher's policy
    Continuous adventitious sounds (CAS) are commonly observed in obstructive pulmonary diseases and are of great clinical interest. However, their evaluation is generally subjective. We have previously developed an automatic ...
  • Sleep stage influence on the autonomic modulation of sleep apnea syndrome 

    Calvo González, Mireia; Jané Campos, Raimon (2019)
    Conference report
    Open Access
    Hypoxia induced by obstructive sleep apnea (OSA) leads to the deregulation of the autonomic nervous system (ANS), resulting in an abnormally increased sympathetic activity. Since ANS modulation varies throughout the night, ...
  • Non-linear HRV analysis to quantify the effects of intermittent hypoxia using an OSA rat model 

    Romero, Daniel; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    In this paper, a non-linear HRV analysis was performed to assess fragmentation signatures observed in heartbeat time series after intermittent hypoxia (IH). Three markers quantifying short-term fragmentation levels, PIP, ...
  • Analysis of time delay between bioimpedance and respiratory volume signals under inspiratory loaded breathing 

    Blanco Almazán, María Dolores; Groenendaal, Willemijn; Catthoor, Francky; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    Bioimpedance is known for its linear relation with volume during normal breathing. For that reason, bioimpedance can be used as a noninvasive and comfortable technique for measuring respiration. The goal of this study is ...
  • Class imbalance impact on the prediction of complications during home hospitalization: a comparative study. 

    Calvo González, Mireia; Cano, Isaac; Henández, Carmen; Ribas, Vicent; Miralles, Felip; Roca, Josep; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    Home hospitalization (HH) is presented as a healthcare alternative capable of providing high standards of care when patients no longer need hospital facilities. Although HH seems to lower healthcare costs by shortening ...
  • Relationship between heart rate excursion and apnea duration in patients with Obstructive Sleep Apnea 

    Solà Soler, Jordi; Giraldo Giraldo, Beatriz; Jané Campos, Raimon; Fiz Fernández, José Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference lecture
    Restricted access - publisher's policy
    Obstructive Sleep Apnea (OSA) is a sleep disorder with a high prevalence in the general population. It is a risk factor for many cardiovascular diseases, and an independent risk factor for cerebrovascular diseases such as ...
  • Onset detection to study muscle activity in reaching and grasping movements in rats 

    Castillo Escario, Yolanda; Rodríguez Cañón, María; García Alías, Guillermo; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    EMG signals reflect the neuromuscular activation patterns related to the execution of a certain movement or task. In this work, we focus on reaching and grasping (R&G) movements in rats. Our objective is to develop an ...
  • Automatic silence events detector from smartphone audio signals: a pilot mHealth system for sleep apnea monitoring at home 

    Castillo Escario, Yolanda; Ferrer Lluís, Ignasi; Montserrat, Josep Maria; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    Obstructive sleep apnea (OSA) is a prevalent disease, but most patients remain undiagnosed and untreated. Recently, mHealth tools are being proposed to screen OSA patients at home. In this work, we analyzed full-night audio ...
