Open Access Abstract Introduction The effect of expiratory endotracheal tube ETT resistance on dynamic lung inflation is unknown. We hypothesized that ETT resistance causes dynamic lung hyperinflation by impeding lung emptying. We further hypothesized that compensation for expiratory ETT resistance by automatic tube compensation ATC attenuates dynamic lung hyperinflation. Methods A ventilator equipped with the original ATC mode and operating in a pressure-targeted mode was connected
