BIOSPIN - Biomedical Signal Processing and Interpretation
La investigació s’emmarca en l’àmbit de l’Enginyeria Biomèdica. S’adreça al disseny i desenvolupament de tècniques avançades de processament de senyals biomèdics multimodals per a la monitorització no invasiva, diagnòstic, prevenció i tractament de malalties. Explorem nous mètodes per a la interpretació d’informació clínicament rellevant dels senyals biomèdics. L’objectiu és millorar el diagnòstic a través de la caracterització dels fenòmens fisiològics, aplicat a les principals malalties cardíacs, respiratories, neurològiques i trastorns del son. També desenvolupem bases de dades de biosenyals, realitzades conjuntament amb els hospitals per avaluar el rendiment dels algoritmes desenvolupats. I estudiem els algorismes proposats en models animals. El grup compta amb múltiples col·laboracions internacionals, incloent empreses i hospitals, d’Europa, Canadà i Estats Units. Actualment, els nostres prototipus s'utilitzen als hospitals per recerca i per a un futur desenvolupament industrial.

Neural respiratory drive estimation in respiratory sEMG with cardiac arrhythmias
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessNeural 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 ... -
Health outcomes from home hospitalization: multisource predictive modeling
(JMIR, 2020-10-07)
Article
Open AccessBackground: Home hospitalization is widely accepted as a cost-effective alternative to conventional hospitalization for selected patients. A recent analysis of the home hospitalization and early discharge (HH/ED) program ... -
Combining bioimpedance and myographic signals for the assessment of COPD during loaded breathing
(2020-05-27)
Article
Open AccessChronic Obstructive Pulmonary Disease (COPD) is one of the most common chronic conditions. The current assessment of COPD requires a maximal maneuver during a spirometry test to quantify airflow limitations of patients. ... -
Hypoxia-induced effects on ECG depolarization by time warping analysis during recurrent obstructive apnea
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open Accessthis 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 ... -
Analysis of Smartphone Triaxial Accelerometry for Monitoring Sleep-Disordered Breathing and Sleep Position at Home
(Institute of Electrical and Electronics Engineers (IEEE), 2020-04-13)
Article
Open AccessObstructive sleep apnea (OSA) is a sleep disorder in which repetitive upper airway obstructive events occur during sleep. These events can induce hypoxia, which is a risk factor for multiple cardiovascular and cerebrovascular ... -
Identifying muscle synergies from reaching and grasping movements in rats
(Institute of Electrical and Electronics Engineers (IEEE), 2020-01-01)
Article
Open AccessReaching and grasping (R&G) is a skilled voluntary movement which is critical for animals. In this work, we aim to identify muscle synergy patterns from R&G movements in rats and show how these patterns can be used to ... -
Cardiovascular coupling-based classification of ischemic and dilated cardiomyopathy patients
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessCardiovascular 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
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policyObstructive 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
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policyThe 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
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policyContinuous 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 ... -
Evaluation of a wearable device to determine cardiorespiratory parameters from surface diaphragm electromyography
(2019)
Article
Open AccessUsing wearable devices in clinical routines could reduce healthcare costs and improve the quality of assessment in patients with chronic respiratory diseases. The purpose of this study is to evaluate the capability of a ... -
Noninvasive assessment of inspiratory muscle neuromechanical coupling during inspiratory threshold loading
(Institute of Electrical and Electronics Engineers (IEEE), 2019-12-16)
Article
Open AccessDiaphragm neuromechanical coupling (NMC), which reflects the efficiency of conversion of neural activation to transdiaphragmatic pressure (Pdi), is increasingly recognized to be a useful clinical index of diaphragm function ...
