Onset and offset estimation of the neural inspiratory time in surface diaphragm electromyography: a pilot study in healthy subjects
(2018-01-01)
Article
Accés restringit per política de l'editorial© 2013 IEEE. This study evaluates the onset and offset of neural inspiratory time estimated from surface diaphragm electromyographic (EMGdi) recordings. EMGdi and airflow signals were recorded in ten healthy subjects ... -
Influence of parameter selection in fixed sample entropy of surface diaphragm electromyography for estimating respiratory activity
(2017-09-01)
Article
Accés obertFixed sample entropy (fSampEn) is a robust technique that allows the evaluation of inspiratory effort in diaphragm electromyography (EMGdi) signals, and has potential utility in sleep studies. To appropriately estimate ... -
Inspiratory muscle activation increases with COPD severity as confirmed by non-invasive mechanomyographic analysis
(2017-05-18)
Article
Accés obertThere is a lack of instruments for assessing respiratory muscle activation during the breathing cycle in clinical conditions. The aim of the present study was to evaluate the usefulness of the respiratory muscle mechanomyogram ... -
Novel approach to continuous adventitious respiratory sound analysis for the assessment of bronchodilator response
(2017-02-08)
Article
Accés obertBackground A thorough analysis of continuous adventitious sounds (CAS) can provide distinct and complementary information about bronchodilator response (BDR), beyond that provided by spirometry. Nevertheless, previous ... -
Performance evaluation of the Hilbert–Huang transform for respiratory sound analysis and its application to continuous adventitious sound characterization
(2016-03)
Article
Accés obertThe use of the Hilbert–Huang transform in the analysis of biomedical signals has increased during the past few years, but its use for respiratory sound (RS) analysis is still limited. The technique includes two steps: ... -
Automatic differentiation of normal and continuous adventitious respiratory sounds using ensemble empirical mode decomposition and instantaneous frequency
(2016-03-01)
Article
Accés obertDifferentiating 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 ... -
Improvement in neural respiratory drive estimation from diaphragm electromyographic signals using fixed sample entropy
(2016-03-01)
Article
Accés obertDiaphragm electromyography is a valuable technique for the recording of electrical activity of the diaphragm. The analysis of diaphragm electromyographic (EMGdi) signal amplitude is an alternative approach for the ... -
Efficiency of mechanical activation of inspiratory muscles in COPD using sample entropy
(2015-12)
Article
Accés restringit per política de l'editorialRespiratory muscle dysfunction is a common problem in patients with chronic obstructive pulmonary disease (COPD) and has mostly been related to pulmonary hyperinflation [1, 2]. Associated diaphragm shortening and deleterious ... -
Classification of patients undergoing weaning from mechanical ventilation using the coherence between heart rate variability and respiratory flow signal”
(Institute of Physics (IOP), 2015-05)
Article
Accés obertWeaning from mechanical ventilation is still one of the most challenging problems in intensive care. Unnecessary delays in discontinuation and weaning trials that are undertaken too early are both undesirable. This study ... -
Time-varying signal analysis to detect high-altitude periodic breathing in climbers ascending to extreme altitude
(2015-03)
Article
Accés obertThis work investigates the performance of cardiorespiratory analysis detecting periodic breathing (PB) in chest wall recordings in mountaineers climbing to extreme altitude. The breathing patterns of 34 mountaineers were ...
