      Article
      Accés obert
      Chronic 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. ...

    • Differences in acoustic features of cough by pneumonia severity in patients with COVID-19: a cross-sectional study 

      M. Davidson, Clare; Caguana, Oswaldo Antonio; Lozano García, Manuel; Arita Guevara, Mariela Lizzeth; Estrada Petrocelli, Luis Carlos; Ferrer Lluís, Ignasi; Castillo Escario, Yolanda; Ausín, Pilar; Gea Guiral, Joaquim; Jané Campos, Raimon (2023-05-01)
      Article
      Accés obert
      Background Acute respiratory syndrome due to coronavirus 2 (SARS-CoV-2) is characterised by heterogeneous levels of disease severity. It is not necessarily apparent whether a patient will develop severe disease or not. ...

    • Multichannel analysis of normal and continuous adventitious respiratory sounds for the assessment of pulmonary function in respiratory diseases 

      Lozano García, Manuel (Universitat Politècnica de Catalunya, 2015-07-15)
      Tesi
      Accés obert
      Respiratory sounds (RS) are produced by turbulent airflows through the airways and are inhomogeneously transmitted through different media to the chest surface, where they can be recorded in a non-invasive way. Due to ...

    • 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)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      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 ...

    • Noninvasive assessment of inspiratory muscle neuromechanical coupling during inspiratory threshold loading 

      Lozano García, Manuel; Estrada Petrocelli, Luis Carlos; Moxham, John; Rafferty, Gerrard F.; Torres Cebrián, Abel; Jolley, J; Jané Campos, Raimon (Institute of Electrical and Electronics Engineers (IEEE), 2019-12-16)
