Linear mixed effects modelling of oxygen desaturation after sleep apneas and hypopneas: a pilot study
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Comunicació de congrés
Accés restringit per política de l'editorialObstructive Sleep Apnea severity is commonly determined after a sleep polysomnographic study by the Apnea-Hypopnea Index (AHI). This index does not contain information about the duration of events, and weights apneas and ... -
Methodology for determine the moment of disconnection of patients of the mechanical ventilation using discrete wavelet transform
(2013)
Comunicació de congrés
Accés obertThe process of weaning from mechanical ventilation is one of the challenges in intensive care units. 66 patients under extubation process (T-tube test) were studied: 33 patients with successful trials and 33 patients who ... -

Power index of the inspiratory flow signal as a predictor of weaning in intensive care units
(2014)
Comunicació de congrés
Accés obertDisconnection from mechanical ventilation, called the weaning process, is an additional difficulty in the management of patients in intensive care units (ICU). Unnecessary delays in the discontinuation process and a weaning ... -
Relationship between heart rate excursion and apnea duration in patients with Obstructive Sleep Apnea
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Comunicació de congrés
Accés restringit per política de l'editorialObstructive Sleep Apnea (OSA) is a sleep disorder with a high prevalence in the general population. It is a risk factor for many cardiovascular diseases, and an independent risk factor for cerebrovascular diseases such as ... -
Respiratory sinus arrhythmia quantified with linear and non-linear techniques to classify dilated and ischemic cardiomyopathy

Text en actes de congrés
Accés obert -
Risk stratification in idiopathic dilated cardiomyopathy patients using cardiovascular coupling analysis
(2019-07-09)
Article
Accés obertCardiovascular diseases are one of the most common causes of death; however, the early detection of patients at high risk of sudden cardiac death (SCD) remains an issue. The aim of this study was to analyze the cardio-vascular ... -
Segmentación del nodo vesical a partir del plano transversal de imágenes ecográficas de la región suprapúbica
(Editorial Universitat Politècnica de València, 2016)
Comunicació de congrés
Accés obertLa retención urinaria después de una cirugía anestésica puede provocar sobre-distensión vesical, impidiendo al paciente miccionar de forma voluntaria. La cateterización es el método más utilizado para solucionar ... -

SVM-based feature selection to optimize sensitivity–specificity balance applied to weaning
(Elsevier, 2013)
Article
Accés restringit per política de l'editorialClassification algorithms with unbalanced data sets tend to produce high predictive accuracy over the majority class, but poor predictive accuracy over the minority class. This problem is very common in biomedical data ... -
Symbolic dynamic analysis of relations between cardiac and breathing cycles in patients on weaning trials
(2010)
Article
Accés restringit per política de l'editorialTraditional time-domain techniques of data analysis are often not sufficient to characterize the complex dynamics of the cardiorespiratory interdependencies during the weaning trials. In this paper, the interactions between ... -
Time-varying respiratory pattern characterization in chronic heart failure patients and healthy subjects
(2009)
Text en actes de congrés
Accés obertPatients with chronic heart failure (CHF) with periodic breathing (PB) and Cheyne–Stokes respiration (CSR) tend to exhibit higher mortality and poor prognosis. This study proposes the characterization of respiratory ... -
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 ... -
Using the heart rate variability for classifying patients with and without chronic heart failure and periodic breathing
(EUETIB, 2013-12)
Comunicació de congrés
Accés obertAssessment of the dynamic interactions between cardiovascular signals can provide valuable information that improves the understanding of cardiovascular control. Heart rate variability (HRV) analysis is known to provide ...
