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 ... -
Surface mechanomyography and electromyography provide non-invasive indices of inspiratory muscle force and activation in healthy subjects
(Nature, 2018-11-16)
Article
Open AccessThe current gold standard assessment of human inspiratory muscle function involves using invasive measures of transdiaphragmatic pressure (Pdi) or crural diaphragm electromyography (oesEMGdi). Mechanomyography is a ... -

Onset and offset estimation of the neural inspiratory time in surface diaphragm electromyography: a pilot study in healthy subjects
(2018-01-01)
Article
Restricted access - publisher's policy© 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
Open AccessFixed 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
Open AccessThere 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
Open AccessBackground 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
Open AccessThe 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
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 ... -
Improvement in neural respiratory drive estimation from diaphragm electromyographic signals using fixed sample entropy
(2016-03-01)
Article
Open AccessDiaphragm 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
Restricted access - publisher's policyRespiratory 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 ...
