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 ...
Función respiratoria en la senectud
(Sociedad Médica de Santiago, 2009)
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
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 ...
Microcirculatory dysfunction and dead-space ventilation in early ARDS: a hypothesis-generating observational study.
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 ...
Capnography reflects ventilation/perfusion distribution in a model of acute lung injury
Background Changes in the shape of the capnogram may reflect changes in lung physiology. We studied the effect of different ventilation/perfusion ratios (V/Q) induced by positive end-expiratory pressures (PEEP) and lung ...
Pulmonary gas exchange in Andean nativos with excessive polycythemia - efecct of hemodilution
(J. Appl. Physiol., 1988)
Pulmonary gas exchange in andean natives (n =8) with excessive high-altitude (3,600-4,200 m) polycythemia (hematocrit 65.1 +- 6.6%) and hipoxemia (arterial PO2 45.6+-5.6 Torr) in the absence of pulmonary or cardiovascular ...
