Tracheal tube cuff pressure is routinely assessed in subjects with tracheal tubes in intensive care units (ICU). The major goal is to prevent aspiration of the colonized secretions from the upper airways and mucosal injuries to the trachea. Hence, its recommended cuff pressures in the range of 20 to 30cmH2O; however, maintaining cuff pressures within these limits can be challenging in clinical practice.
The cuff pressure stability depends on several factors, such as compliance of the trachea and the cuff, the subject and cuff positions, the cuff volume and the body temperature. Because these factors vary continuously during an ICU stay, cuff pressure must be monitored and adjusted routinely.
A slight intracuff pressure excess, even for a short time, is sufficient to impair the local blood supply and cause hyperemia and hemorrhage in the tracheal wall at the cuff contact area. It’s been showed that low cuff pressures lead to loss and disruption of tracheal epithelium, cilia loss, inflammation or blood cell infiltration in the cuff contact area.
Nevertheless, maintaining tracheal tube cuff pressure above 20cmH2O is fundamental to prevent the leakage of contaminated supraglottic secretions past the cuff. There are several factors related to ventilator-associated pneumonia (VAP), such as impaired host defense and mucociliary clearance, gastric and upper respiratory tract colonization and microorganism virulence; however, the leakage of contaminated secretions past the cuff is the major etiologic factor for VAP. VAP is one of the most frequent infections in ICU patients, with a prevalence between 10 and 27%. Preventing the aspiration of respiratory secretions from the supraglottic space and monitoring cuff pressure are well-proven techniques to prevent VAP.
