Inflation and deflation of the cuff of an endotracheal tube (ETT) is a routine part of airway management. Inflation of the cuff ensures a seal that enables intermittent positive pressure ventilation and provides safety from aspiration of gastric contents.[1] Like inflation, deflation of the ETT cuff carries its own importance prior to extubation and during nasotracheal intubation. Quantification of cuff inflation is translated as positive intracuff pressure, which is widely measured using a cuff manometer.[2] However, there is no provision to quantify the intracuff pressure of a deflated cuff. We report a case indicating negative intracuff pressure inside a deflated cuff.
