Assessment of dead-space ventilation in patients with acute respiratory distress syndrome: a prospective observational study.
BACKGROUND Physiological dead space (VD/VT) represents the fraction of ventilation not participating in gas exchange. In patients with acute respiratory distress syndrome (ARDS), VD/VT has prognostic value and can be used to guide ventilator settings. However, VD/VT is rarely calculated in clinical practice, because its measurement is perceived as challenging. Recently, a novel technique to cal...
متن کاملDead space in acute respiratory distress syndrome: more than a feeling!
Why clinicians are slow to implement advances in diagnosis and treatment from well-designed clinical trials is a continuously debated question in critical care. For instance, prone positioning significantly improves mortality in patients with severe acute respiratory distress syndrome (ARDS), but the usefulness of recruitment measures in this population is still under debate. Nevertheless, a re...
متن کاملPulmonary dead-space fraction as a risk factor for death in the acute respiratory distress syndrome.
BACKGROUND No single pulmonary-specific variable, including the severity of hypoxemia, has been found to predict the risk of death independently when measured early in the course of the acute respiratory distress syndrome. Because an increase in the pulmonary dead-space fraction has been described in observational studies of the syndrome, we systematically measured the dead-space fraction early...
متن کاملPotential effects of corticosteroids on physiological dead-space fraction in acute respiratory distress syndrome.
BACKGROUND Increased dead-space fraction is common in patients with persistent acute respiratory distress syndrome (ARDS). We evaluated the changes in the oxygenation and dead-space fraction in patients with persistent ARDS after corticosteroid therapy. METHODS This was a non-randomized non-placebo, controlled observational study including 19 patients with persistent ARDS treated with cortic...
متن کاملAlveolar dead-space response to activated protein C in acute respiratory distress syndrome.
We report a complicated case of acute respiratory distress syndrome (ARDS) from severe sepsis, in which we measured the ratio of physiologic dead space to tidal volume (V(D)/V(T)) with volumetric capnography prior to, during, and after therapy with human recombinant activated protein C. Previous studies hypothesized that early in ARDS, elevated V(D)/V(T) primarily reflects increased alveolar V(...
