Figure 1From: Cardiac index and oxygen delivery during low and high tidal volume ventilation strategies in patients with acute respiratory distress syndrome: a crossover randomized clinical trialValues of cardiac index throughout the study for each individual, with baseline and final values for low and high tidal volume (TV) ventilation strategy. In the study, the sequence of low TV and high TV ventilation was randomized, so that the figure does not provide any information about the actual order in which the two ventilation strategies were applied.Back to article page
