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 ...
Sildenafil for treating patients with COVID-19 and perfusion mismatch: a pilot randomized trial
(BioMed Central Ltd, 2022-01)
Background: SARS-CoV-2 seems to affect 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 ...
Capnography reflects ventilation/perfusion distribution in a model of acute lung injury
(WILEY-BLACKWELL, 2011)
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 ...
Anatomical and functional intrapulmonary shunt in acute respiratory distress syndrome
(LIPPINCOTT WILLIAMS & WILKINS, 2008)
Objectives. The lung-protective strategy employs positive end expiratory pressure to keep open otherwise collapsed lung regions (anatomical recruitment). Improvement in venous admixture with positive end-expiratory pressure ...
