Fig. 6From: Patient–ventilator asynchrony in acute brain-injured patients: a prospective observational studyA significant difference in the asynchrony index was found among different analgesia/sedation strategies (p < 0.001). Individual data, median, and interquartile ranges are shown. Asynchrony index during combined administration of opioids and sedatives was significantly higher than those during single use of opioids or sedatives, as well as no use of these two types of drugs. No significant difference was found in asynchrony index among the latter three conditionsBack to article page
