摘要： Cuff pressure modulation results in decreased severity of injury to the subglottic region and upper trachea. A simple device is capable of modulating the pressure in the cuff of a regular endotracheal tube, by coordinating the pressure level to be maximal during the inspiratory phase and minimal during the expiratory phase. This allowed for regular positive airway pressure ventilation as during inspiration the seal was maintained between the ETT and the tracheal mucosa by the inflated cuff, but during expiration cuff deflation allowed the cuff pressure to drop in the subglottic and tracheal area.
