摘要：
A method of sealing a trachea is provided that includes inserting a tracheal tube having an inflatable cuff made of a compliant material into a trachea. The method includes inflating the inflatable cuff with a fluid to a first pressure that exceeds a second pressure necessary to create a seal between the inflatable cuff and the tracheal wall. The method includes deflating the inflatable cuff by releasing a first pressure to allow the fluid to flow out of the inflatable cuff without applying vacuum pressure to the fluid while evaluating a rate of change of pressure of the fluid in the inflatable cuff. The method includes identifying a variance in the rate of change of pressure corresponding to a third pressure at which the inflatable cuff separates from the tracheal wall, determining the second pressure by analyzing the third pressure, and reinflating the inflatable cuff to the second pressure.
