Abstract
An airway management device is provided that may adjust the inflation level of a cuff associated with an endotracheal tube. The cuff inflation may be adjusted in response to an increase in carbon dioxide levels above the cuff, which may indicate a poor seal of the cuff against the tracheal walls, as well in response to a measured intracuff pressure. By using information about the seal quality of the cuff together with information about the cuff pressure, the inflation of the cuff can be adjusted to minimize cuff inflation pressure while maintaining a high quality tracheal seal.
