Cintigrafía de ventilación y perfusión en el manejo del tromboembolismo pulmonar
(Sociedad Médica de Santiago, 2000)
Fuzzy modeling of electrical impedance tomography images of the lungs
(Faculdade de Medicina / USP, 2008)
OBJECTIVES: Aiming to improve the anatomical resolution of electrical impedance tomography images, we developed a fuzzy model based on electrical impedance tomography's high temporal resolution and on the functional pulmonary ...
Sildenafil for treating patients with COVID-19 and perfusion mismatch: a pilot randomized trial
(BMC, 2022)
Background: SARS-CoV-2 seems to afect the regulation of pulmonary perfusion. Hypoperfusion in areas of well-aerated lung parenchyma results in a ventilation–perfusion mismatch that can be characterized using subtraction ...

Mechanisms underlying gas exchange alterations in an experimental model of pulmonary embolism
(Associação Brasileira de Divulgação Científica, 2006)
Mechanisms of worsening gas exchange during acute exacerbations of chronic obstructive pulmonary disease
(1997)
This study was undertaken to investigate the mechanisms that determine abnormal gas exchange during acute exacerbations of chronic obstructive pulmonary disease (COPD). Thirteen COPD patients, hospitalized because of an ...
Modeling lung perfusion abnormalities to explain early COVID-19 hypoxemia
Early stages of the novel coronavirus disease (COVID-19) are associated with silent hypoxia
and poor oxygenation despite relatively minor parenchymal involvement. Although speculated that such paradoxical findings may be ...
Microcirculatory dysfunction and dead-space ventilation in early ARDS: a hypothesis-generating observational study.
(2020)
Abstract
Background
Ventilation/perfusion inequalities impair gas exchange in acute respiratory distress syndrome (ARDS). Although increased dead-space ventilation (VD/VT) has been described in ARDS, its mechanism is not ...
