Caracterización de pacientes con diferentes niveles de riesgo cardiovascular mediante diagramas de Poincaré [PDF]

open access: yes, 2016
En 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 dilatada (DCM), y 35 sujetos sanos ...

Oxygenation and Blood Volume Periodic Waveforms in the Brain [PDF]

open access: yesarXiv, 2011
Results of an experiment are presented whose aim is to explore the relationship between respiration and cerebral oxygenation. Measurements of end tidal CO2 (EtCO2) were taken simultaneously with cerebral oxygen saturation (rSO2) using the INVOS Cerebral Oximeter of Somanetics.

Normative Cerebral Perfusion Across the Lifespan [PDF]

open access: yesarXiv
Cerebral perfusion plays a crucial role in maintaining brain function and is tightly coupled with neuronal activity. While previous studies have examined cerebral perfusion trajectories across development and aging, precise characterization of its lifespan dynamics has been limited by small sample sizes and methodological inconsistencies. In this study,

Simple exercises that significantly increase cerebral blood flow and cerebral oxygenation [PDF]

open access: yesarXiv, 2011
We tested the hypothesis that simple exercises may significantly increase cerebral blood flow (CBF) and/or cerebral oxygenation. Eighteen subjects ranging in age from nineteen to thirty nine participated in a four-stage study during which measurements of end tidal CO_2 (EtCO2 - by capnometer) and local brain oxygenation (by near-infrared spectroscopy ...
