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 ...

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)

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 ...

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, ...

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 ...
Analysis of QRS loop in the vectorcardiogram of patients with Chagas' disease
(2010)

In the present work, we have studied the QRS loop in the Vectorcardiogram (VCG) of 95 chronic chagasic patients classified in different groups (I, II and III) according to their degree of myocardial damage. For comparison, ...
Estimation of instantaneous frequency from empirical mode decomposition on respiratory sounds analysis
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Text en actes de congrés.

Text en actes de congrés.
Accés restringit per política de l'editorial
Instantaneous frequency (IF) calculated by empirical mode decomposition (EMD) provides a novel approach to analyze respiratory sounds (RS). Traditionally, RS have been
analyzed using classical time-frequency distributions, ...
