Frequency Of Inappropriate Endotracheal Tube Cuff Pressure And Its Variability In Patients Undergoing Prolonged Surgery: A Prospective Observational Study.

Background: Endotracheal tube (ETT) is inserted into the trachea to maintain airway patency. Maintaining adequate ETT cuff pressure is important to ensure a proper seal to lower the risk of aspiration and tracheal trauma. This study was designed to assess the frequency of inappropriate ETT cuff pressure at the time of intubation and variation in ETT pressure at the end of a prolonged surgery.
