A novel strategy to fit and validate physiological models: a case study of acardiorespiratory model for simulation of incremental aerobic exercise
(2023-03-01)
Article
Open AccessApplying complex mathematical models of physiological systems is challenging due to the large number of parameters. Identifying these parameters through experimentation is difficult, and although procedures for fitting and ... -
A synchronization system for the analysis of biomedical signals recorded with different devices from mechanically ventilated patients
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Conference lecture
Restricted access - publisher's policyConducting research associated with mechanically ventilated patients often requires the recording of several biomedical signals to dispose of multiple sources of information to perform a robust analysis. This is especially ... -
An improved dynamic model for the respiratory response to exercise
(2018-02-07)
Article
Open AccessRespiratory system modeling has been extensively studied in steady-state conditions to simulate sleep disorders, to predict its behavior under ventilatory diseases or stimuli and to simulate its interaction with mechanical ... -
Assessment of weaning indexes based on diaphragm activity in mechanically ventilated subjects after cardiovascular surgery. A pilot study
(2017-06)
Article
Open AccessOBJECTIVE: The aim of this pilot study was to evaluate the feasibility of surface electromyographic signal derived indexes for the prediction of weaning outcomes among mechanically ventilated subjects after cardiac surgery. ... -
Estimation of work of breathing from respiratory muscle activity in spontaneous ventilation: A pilot study
(Multidisciplinary Digital Publishing Institute, 2019-05-01)
Article
Open AccessWork of breathing (WOB) offers information that may be relevant to determine the patient’s status under spontaneous mechanical ventilation in Intensive Care Unit (ICU). Nowadays, the most reliable technique to measure WOB ... -

Novel Modeling of Work of Breathing for Its Optimization During Increased Respiratory Efforts
(2016-09-01)
Article
Open AccessThe respiratory control system is one of the most complex physiological systems, whose controller has been extensively modeled based on the criterion of minimizing work of breathing (WOB). However, cost functions and their ... -
Optimization techniques in respiratory control system models
(2016-11-01)
Article
Open AccessOne of the most complex physiological systems whose modeling is still an open study is the respiratory control system where different models have been proposed based on the criterion of minimizing the work of breathing ... -
Potential clinical application of surface electromyography as indicator of neuromuscular recovery during weaning tests after organophosphate poisoning
(2017-06)
Article
Open AccessThis study aimed to explore the usefulness of measuring respiratory muscle activity in mechanically ventilated patients suffering from acute organophosphate poisoning, with a view towards providing complementary information ... -
Precuneus failures in subjects of the PSEN1 E280A family at risk of developing Alzheimer's disease detected using quantitative electroencephalography
(2017-07-01)
Article
Open AccessPresenilin-1 (PSEN1) mutations are the most common cause of familial early onset Alzheimer's disease (AD). The PSEN1 E280A (E280A) mutation has an autosomal dominant inheritance and is involved in the production of amyloid-ß. ... -
Successful object encoding induces increased directed connectivity in presymptomatic early-onset Alzheimer's disease
(2017-01-01)
Article
Open AccessBackground: Recent studies report increases in neural activity in brain regions critical to episodic memory at preclinical stages of Alzheimer’s disease (AD). Although electroencephalography (EEG) is widely used in AD ... -
