  • Relationship Between Heart Rate Recovery and Disease Severity in Chronic Obstructive Pulmonary Disease Patients 

    Blanco Almazán, María Dolores; Romero Pérez, Daniel; Groenendaal, Willemijn; Lijnen, Lien; Smeets, Christophe; Ruttens, David; Catthoor, Francky; Jané Campos, Raimon (2020)
    Conference lecture
    Open Access
    Chronic obstructive pulmonary disease (COPD) patients exhibit impaired autonomic control which can be assessed by heart rate variability analysis. The study aims to evaluate the cardiac autonomic responses of COPD patients ...
  • Spatial distribution of normal lung sounds in healthy individuals under varied inspiratory load and flow conditions 

    Lozano García, Manuel; M. Davidson, Clare; Prieto Ramón, Carlos; Moxham, John; Rafferty, Gerrard F.; Jolley, J; Jané Campos, Raimon
    Conference report
    Open Access
    Respiratory sounds yield pertinent information about respiratory function in both health and disease. Normal lung sound intensity is a characteristic that correlates well with airflow and it can therefore be used to quantify ...
  • Performance evaluation of fixed sample entropy for lung sound intensity estimation 

    Lozano García, Manuel; Nuhic, Jasna; Moxham, John; Rafferty, Gerrard F.; Jolley, J; Jané Campos, Raimon
    Conference report
    Open Access
    ung sound (LS) signals are often contaminated by impulsive artifacts that complicate the estimation of lung sound intensity (LSI) using conventional amplitude estimators. Fixed sample entropy (fSampEn) has proven to be ...
  • Cardiac comorbidities in COPD patients explained through HRV analysis and respiratory indices 

    Romero Pérez, Daniel; Blanco Almazán, María Dolores; Groenendaal, Willemijn; Lijnen, Lien; Smeets, Christophe; Ruttens, David; Catthoor, Francky; Jané Campos, Raimon (2020)
    Conference lecture
    Open Access
    Chronic obstructive pulmonary disease (COPD) patients exhibit depressed heart rate variability (HRV), while comorbidities may worsen the patients’ prognosis. We investigated whether HRV analyis, clinical markers of disease ...
  • Neural respiratory drive estimation in respiratory sEMG with cardiac arrhythmias 

    Estrada Petrocelli, Luis Carlos; Jané Campos, Raimon; Torres Cebrián, Abel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    Neural respiratory drive as measured by the electromyography allows the study of the imbalance between the load on respiratory muscles and its capacity. Surface respiratory electromyography (sEMG) is a non-invasive tool ...
  • 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, ...
