Performance comparison of the new automated cuff pressure controller with the currently available device in a clinical setting. a The peak cuff pressure value for the newly developed automated cuff pressure controller (Cuff-Keeper), automated cuff pressure controller, and intermittent monitoring method as measured by a cuff pressure gauge. *p < 0.0001 vs. device A max value. # p < 0.0001 vs. device B max value. b Number of times the cuff pressure exceeded 35 cmH2O over a 24-h period using the newly developed automated cuff pressure controller (Cuff-Keeper), automated cuff pressure controller, and intermittent monitoring method with a cuff pressure gauge. The data are shown as boxes with the central mark indicating the median. The edges of the box are the 25th and 75th percentiles. The whiskers show the minimum and maximum values. *p < 0.0001 vs. device A. # p < 0.0001 vs. device B
