    • Dead space ventilation-related indices bedside tools to evaluate the ventilation and perfusion relationship in patients with acute respiratory distress syndrome
    Authors: Mingjia, Zheng;  Advisor: -;  Co-Author: - (2023)

    Cumulative evidence has demonstrated that the ventilatory ratio closely correlates with mortality in acute respiratory distress syndrome (ARDS), and a primary feature in coronavirus disease 2019 (COVID-19)-ARDS is increased dead space that has been reported recently. Thus, new attention has been given to this group of dead space ventilation-related indices, such as physiological dead space fraction, ventilatory ratio, and end-tidal-to-arterial PCO2 ratio, which, albeit distinctive, are all global indices with which to assess the relationship between ventilation and perfusion.
