      Article
      Open Access
      Breathing pattern has been shown to be different in chronic obstructive pulmonary disease (COPD) patients compared to healthy controls during rest and walking. In this study we evaluated respiratory parameters and the ...

    • Cardiac comorbidities in COPD patients explained through HRV analysis and respiratory indices 

      Romero Pérez, Daniel; Blanco Almazán, María Dolores; Groenendaal, Willemijn; Lijnen, Lien; Smeets, Christophe; Ruttens, David; Catthoor, Francky; Jané Campos, Raimon (2020)
      Conference lecture
      Open Access
      Chronic obstructive pulmonary disease (COPD) patients exhibit depressed heart rate variability (HRV), while comorbidities may worsen the patients’ prognosis. We investigated whether HRV analyis, clinical markers of disease ...

    • Chest movement and respiratory volume both contribute to thoracic bioimpedance during loaded breathing 

      Blanco Almazán, María Dolores; Groenendaal, Willemijn; Catthoor, Francky; Jané Campos, Raimon (Nature, 2019-12-27)
      Article
      Open Access
      Bioimpedance has been widely studied as alternative to respiratory monitoring methods because of its linear relationship with respiratory volume during normal breathing. However, other body tissues and fluids contribute ...

    • Combining bioimpedance and myographic signals for the assessment of COPD during loaded breathing 

      Blanco Almazán, María Dolores; Groenendaal, Willemijn; Lozano García, Manuel; Estrada Petrocelli, Luis Carlos; Lijnen, Lien; Smeets, Christophe; Catthoor, Francky; Jané Campos, Raimon (2021-01-01)
      Article
      Open Access
      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. ...

    • Detection of respiratory phases to estimate breathing pattern parameters using wearable bioimpendace
