Acoustic analysis of snoring sound in patients with simple snoring and obstructive sleep apnoea
(1996-11-09)
Article
Open AccessSnoring, a symptom which may indicate the presence of the obstructive sleep apnoea syndrome (OSA), is also common in the general population. Recent studies have suggested that the acoustic characteristics of snoring sound ... -
An invasive and a noninvasive approach for the automatic differentiation of obstructive and central hypopneas
(2010-04-15)
Article
Open AccessThe automatic differentiation of obstructive and central respiratory events is a major challenge in the diagnosis of sleep-disordered breathing. Esophageal pressure (Pes) measurement is the gold-standard method to ... -

Analysis of QRS loop in the vectorcardiogram of patients with Chagas' disease
(2010)
Conference report
Open AccessIn the present work, we have studied the QRS loop in the Vectorcardiogram (VCG) of 95 chronic chagasic patients classified in different groups (I, II and III) according to their degree of myocardial damage. For comparison, ... -
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 ... -
Analysis of time delay between bioimpedance and respiratory volume signals under inspiratory loaded breathing
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessBioimpedance 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 ... -

Article
Open AccessBioimpedance 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 ... -
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 ... -
Análisis de la intensidad de los sonidos respiratorios para el diagnóstico de la parálisis frénica unilateral
(2014)
Conference lecture
Open AccessEl análisis acústico de la intensidad de los sonidos respiratorios (ISR) es una medida indirecta y no invasiva de la función respiratoria, que permite comparar la actividad en los dos hemitórax de los pacientes con parálisis ... -
Análisis de sonidos adventicios continuos en pacientes asmáticos mediante el espectro de Hilbert
(Sociedad Española de Ingeniería Biomédica (SEIB), 2015)
Conference report
Restricted access - publisher's policyLos sonidos adventicios continuos (CAS) son uno de los principales síntomas del asma. Dada su importancia clínica, el análisis de estas señales requiere del uso de técnicas que permitan segmentarlas y caracterizarlas con ... -
Assessment of inspiratory muscle activation using surface diaphragm mechanomyography and crural diaphragm electromyography
(2018)
Conference report
Restricted access - publisher's policyThe relationship between surface diaphragm mechanomyography (sMMGdi), as a noninvasive measure of inspiratory muscle mechanical activation, and crural diaphragm electromyography (oesEMGdi), as the invasive gold standard ... -
Assessment of respiratory flow cycle morphology in patients with chronic heart failure
(2017-02-01)
Article
Open AccessBreathing pattern as periodic breathing (PB) in chronic heart failure (CHF) is associated with poor prognosis and high mortality risk. This work investigates the significance of a number of time domain parameters for ... -
Assessment of respiratory muscle activity with surface electromyographic signals acquired by concentric ring electrodes
(2018)
Conference lecture
Restricted access - publisher's policyThe assessment of respiratory muscle activity by surface electromyography (sEMG) is a promising noninvasive technique for the diagnosis and monitoring of chronic obstructive pulmonary disease. The diaphragm is the ... -
Automatic differentiation of normal and continuous adventitious respiratory sounds using ensemble empirical mode decomposition and instantaneous frequency
(2016-03-01)
Article
Open AccessDifferentiating normal from adventitious respiratory sounds (RS) is a major challenge in the diagnosis of pulmonary diseases. Particularly, continuous adventitious sounds (CAS) are of clinical interest because they reflect ... -
Automatic differentiation of obstructive and central hypopneas with esophageal pressure measurement during sleep
(2009)
Conference report
Open AccessThe differentiation between obstructive and central respiratory events is one of the most recurrent tasks in the diagnosis of sleep disordered breathing. Esophageal pressure measurement is the gold-standard method to ... -
Automatic event detector from smartphone accelerometry: Pilot mHealth study for obstructive sleep apnea monitoring at home
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessObstructive sleep apnea (OSA) is a common disorder with a low diagnosis ratio, leaving many patients undiagnosed and untreated. In the last decades, accelerometry has been found to be a feasible solution to obtain respiratory ... -
Automatic non-invasive differentiation of obstructive and central hypopneas with nasal airflow compared to esophageal pressure
(2010)
Conference report
Open AccessThe differentiation of obstructive and central respiratory events is a major challenge in the diagnosis of sleep disordered breathing. Esophageal pressure (Pes) measurement is the gold-standard method to identify these ... -
Automatic silence events detector from smartphone audio signals: a pilot mHealth system for sleep apnea monitoring at home
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessObstructive 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 ... -
