Ventilation distribution calculation using 4D CT has shown promising potential in several clinical applications. This study evaluated the direct geometric ventilation calculation method, namely the ΔV method, with xenon-enhanced CT (XeCT) ventilation data from four sheep, and compared it with two other published meth-ods, the Jacobian and the Hounsfield unit (HU) methods. Spearman correlation c...
OBJECTIVE To evaluate whether ventilation strategies that target alveolar stabilization and prevention of atelectrauma would be associated with more favorable physiologic outcomes in a combined model of acute lung injury. METHODS Thirty-nine rabbits were instrumented and ventilated with FiO(2) of 1.0. Combined lung injury was induced by an infusion of lipopolysaccharide and tracheal saline la...
OBJECTIVE The optimum strategy for mechanical ventilation in a child with status asthmaticus is not established. Volume-controlled ventilation continues to be the traditional approach in such children. Pressure-controlled ventilation may be theoretically more advantageous in allowing for more uniform ventilation. We describe our experience with pressure-controlled ventilation in children with s...
Noninvasive ventilation has been available for over 100 years. In the past 25 years, relatively lightweight, portable ventilators and comfortable interfaces have become available that have allowed for full-time noninvasive ventilation. In motivated individuals who have access to centers with expertise in nocturnal and diurnal ventilation, continuous noninvasive ventilation is quite feasible. Th...
