Analysis of cardiorespiratory interaction in patients submitted to the T-tube test in the weaning process implementing symbolic dynamics and neural networks
(2018)
Conference report
Restricted access - publisher's policyThe determination of the optimal time of the patients in weaning trial process from Mechanical Ventilation (MV), between patients capable of maintaining spontaneous breathing and patients that fail to maintain spontaneous ... -
Analysis of the breathing pattern in elderly patients using the Hurst exponent applied to the respiratory flow signal
(2014)
Conference report
Restricted access - publisher's policyDue to the increasing elderly population and the extensive number of comorbidities that affect them, studies are required to determine future increments in admission to emergency departments. Some of these studies could ... -
Analysis of the cardiorespiratory pattern of patients undergoing weaning using artificial intelligence
(2023-03-01)
Article
Open AccessThe optimal extubating moment is still a challenge in clinical practice. Respiratory pattern variability analysis in patients assisted through mechanical ventilation to identify this optimal moment could contribute to this ... -
Analysis of the respiratory pattern variability of patients in weaning process using autoregressive modeling techniques
(2011)
Conference report
Restricted access - publisher's policyOne of the most challenging problems in intensive care is the process of discontinuing mechanical ventilation, called weaning process. An unnecessary delay in the discontinuation process and an early weaning trial are ... -
Análisis de coherencia y densidad espectral de potencia entre las señales de flujo respiratorio y la variabilidad del ritmo cardiaco en pacientes en proceso de extubación
(2009)
Conference lecture
Open AccessUn considerable porcentaje de pacientes en procesos de extubación tienen problemas para mantener una respiración espontanea con la subsiguiente reintubación, razón por la cual se requiere de una técnica que no base sus ... -
Análisis de la señal ECG en pacientes con enfermedad de Párkinson
(2016)
Conference lecture
Open Access -
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 ... -
Baroreflex activity through the analysis of the cardio-respiratory variability influence over blood pressure in cardiomyopathy patients
(Frontiers Media SA, 2023-08-10)
Article
Open AccessA large portion of the elderly population are affected by cardiovascular diseases. Early prognosis of cardiomyopathies remains a challenge. The aim of this study was to classify cardiomyopathy patients by their etiology ... -
Breathing pattern characterization in chronic heart failure patients using the respiratory flow signal
(2010-07-08)
Article
Restricted access - publisher's policyThis study proposes a method for the characterization of respiratory patterns in chronic heart failure (CHF) patients with periodic breathing (PB) and nonperiodic breathing (nPB), using the flow signal. Autoregressive ... -
Caracterización de pacientes con diferentes niveles de riesgo cardiovascular mediante diagramas de Poincaré
(Editorial Universitat Politècnica de València, 2016)
Conference lecture
Open AccessEn este trabajo se propone caracterizar la dinámica no-lineal de los sistemas cardíaco, vascular y respiratorio a partir de los diagramas de Poincaré. Se han analizado 46 pacientes con cardiomiopatía isquémica (ICM) o ... -
Caracterización de pacientes isquémicos y dilatados a partir de las señales ECG y de presión sanguínea
(2015)
Conference report
Open Access -
Caracterización y análisis del ECG, la presión sanguínea y el flujo respiratorio en sujetos sanos
(EUETIB, 2013-12)
Conference lecture
Open AccessEl estudio del sistema cardiovascular y del sistema respiratorio, así como su interacción, sigue siendo actualmente un importante campo de investigación en la práctica clínica. Una forma de analizar estos sistemas es a ... -
Cardiorespiratory phase synchronization in OSA subjects during wake and sleep states
(2015)
Conference report
Restricted access - publisher's policyCardiorespiratory Phase Synchronization (CRPS) is a manifestation of coupling between cardiac and respiratory systems complementary to Respiratory Sinus Arrhythmia. In this work, we investigated CRPS during wake and sleep ... -
Cardiorespiratory phase synchronization increases during certain mental stimuli in healthy subjects
(2018)
Conference report
Open AccessSeveral neurological and mechanical non-linear mechanisms relate the respiratory and cardiovascular systems to one another. Besides the well-known modulation of heart rate by respiration, another form of non-linear interaction ... -
Cardiovascular coupling-based classification of ischemic and dilated cardiomyopathy patients
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessCardiovascular diseases are one of the most common causes of death in elderly patients. The etiology of cardiomyopathies is difficult to discern clinically. The objective of this study was to classify cardiomyopathy patients ... -
Characterization and classification of patients with different levels of cardiac death risk by using Poincaré plot analysis
(2017)
Conference lecture
Open AccessCardiac death risk is still a big problem by an important part of the population, especially in elderly patients. In this study, we propose to characterize and analyze the cardiovascular and cardiorespiratory systems using ... -
Characterization of blood pressure signal considering low and high risk stratification in cardiomyopathy patients
(2013)
Conference report
Restricted access - publisher's policyIschemic and dilated cardiomyopathy are associated with disorders of myocardium. Using the blood pressure (BP) signal and the values of the ventricular ejection fraction, we obtained parameters for stratifying cardiomyopathy ... -
Characterization of cardiac and respiratory system of healthy subjects in supine and sitting position
(Springer, 2019-09)
Part of book or chapter of book
Restricted access - publisher's policyStudies based on the cardiac and respiratory system have allowed a better knowledge of their behavior to contribute with the diagnosis and treatment of diseases associated with them. The main goal of this project was to ... -
Characterization of HRV and QRS slope during audiovisual stimulation
