1. Asynchrony index (%) during invasive and noninvasive ventilation (NIV) relative to body weight.
Asynchrony index (%) during invasive and noninvasive ventilation (NIV) relative to body weight. A: PC-CSV in invasive ventilation. B: PC-CMV in invasive ventilation. C: PC-CSV in NIV. D: PC-CMV in NIV. Boxes represent the interquartile range 25th and the 75th percentiles; center lines denote the median. Bars represent maximum and minimum values. Data across all leak levels were compared between ventilators at each body weight. A single dash at 100% indicates non-run, meaning that the ventilator could not be triggered by simulated breaths under the baseline leak, and further leak was not applied (asynchrony index = 100%). Avea and Servo-i are shown with and without a proximal flow sensor. * = P < .05, ** = P < .01, *** = P < .001 vs PB980. † = P < .05, †† = P < .01, ††† = P < .001 vs V500. ‡ = P < .05, ‡‡ = P < .01, and ‡‡‡ = P < .001 vs PB840. § = P < .001 vs Servo-i with and without a flow sensor.
