Relationship between dynamic distending pressure and pressure support at a respiratory rate of 24/min (a) and 36/min (b). Comparisons between dynamic distending pressure under pressure support and T-piece breathing tubes are presented (p < 0.05 by Tukey’s multiple-comparisons test). Error bars represent standard deviation values. Asterisk denotes that dynamic distending pressure of 3.5-mm tubes is significantly higher than that at T-piece breathing. Number sign denotes that dynamic distending pressure of 3.0-mm tubes is significantly higher than that at T-piece breathing
