Automatic differentiation of obstructive and central hypopneas with esophageal pressure measurement during sleep
(2009)
Text en actes de congrés.
Accés obert
Text en actes de congrés.
Accés obert
The differentiation between obstructive and
central respiratory events is one of the most recurrent tasks in the diagnosis of sleep disordered breathing. Esophageal
pressure measurement is the gold-standard method to ...
Correntropy-based spectral characterization of respiratory Patterns in patients with chronic heart failure
(2010-08)
Article.
Accés obert
Article.
Accés obert
A correntropy-based technique is proposed for the characterization and classification of respiratory flow signals in chronic heart failure (CHF) patients with periodic or nonperiodic breathing (PB or nPB, respectively) and ...
Comparison of upper airway respiratory resistance measurements with the esophageal pressure/airflow relationship during sleep

Measurement of upper airway resistance is of
interest in sleep disordered breathing to estimate upper airway patency. Resistance is calculated with the airflow and respiratory effort signals. However, there is no consensus ...
Multistate Lempel-Ziv (MLZ) index interpretation as a measure of amplitude and complexity changes
(2009)
Text en actes de congrés.
Accés obert
Text en actes de congrés.
Accés obert
The Lempel-Ziv complexity (LZ) has been widely used to evaluate the randomness of finite sequences. In general, the LZ complexity has been used to determine the complexity grade present in biomedical signals. The LZ ...
Automatic non-invasive differentiation of obstructive and central hypopneas with nasal airflow compared to esophageal pressure
(2010)
Text en actes de congrés.
Accés obert
Text en actes de congrés.
Accés obert
The differentiation of obstructive and central respiratory events is a major challenge in the diagnosis of sleep
disordered breathing. Esophageal pressure (Pes) measurement is the gold-standard method to identify these ...
Feasibility of noninvasive single-channel automated differentiation of obstructive and central hypopneas with nasal airflow
(2013-03)
Article.
Accés restringit per política de l'editorial
Article.
Accés restringit per política de l'editorial
Background: The identification of obstructive and central hypopneas is considered challenging in clinical practice.
Presently, obstructive and central hypopneas are usually not differentiated or scores lack reliability ...

Evaluation of the respiratory muscular function by means of diaphragmatic mechanomyographic signals in copd patients
(2009)
Text en actes de congrés.
Accés obert
Text en actes de congrés.
Accés obert
The study of mechanomyographic (MMG) signals
of respiratory muscles is a promising technique in order to evaluate the respiratory muscular effort. In this work MMG
signals from left and right hemidiaphragm (MMGl and MMGr, ...
Diferenciación automática de hipopneas mediante la señal de presión esofágica durante el sueño

Text en actes de congrés.
Accés restringit per política de l'editorial
La diferenciación entre hipopneas obstructivas y centrales es uno de los trabajos más recurrentes en el diagnóstico de los trastornos respiratorios del sueño. La medición de presión esofágica (Pes) es el método gold-standard ...
Detecting unilateral phrenic paralysis by acoustic respiratory analysis
(2014-04-09)
Article.
Accés obert
Article.
Accés obert
The consequences of phrenic nerve paralysis vary from a considerable reduction in respiratory function to an apparently normal state. Acoustic analysis of lung sound intensity (LSI) could be an indirect non-invasive ...
