1 The cause of asynchrony during volume-targeted ventilation and total asynchrony index.
The cause of asynchrony during volume-targeted ventilation and total asynchrony index. A: Volume-targeted pressure control continuous spontaneous ventilation. B: Volume-targeted pressure control continuous mandatory ventilation. The bars show total asynchrony index (%). Each asynchrony type across all body weights and leak levels was compared. The Servo-i and PB980 were used with and without the proximal flow sensor. A: * P = < .001 vs V500 for auto-triggering, † = P < .001 vs PB980 without sensor for double-triggering; clinically significant (>10%). B: * = P < .05 vs V500 for auto-triggering, ‡ = P < .001 vs PB980 without sensor for double-triggering; clinically significant (>10%). Each asynchrony was compared with the lowest percentage for that type of asynchrony. Taiga Itagaki et al. Respir Care 2017;62:10-21 (c) 2012 by Daedalus Enterprises, Inc.
