cuffed tracheostomy tube
Tracheostomy tube equipped with an inflatable balloon cuff to create a seal in the trachea for mechanical ventilation or airway protection.
Full Definition
A cuffed tracheostomy tube is a specialized airway device featuring an inflatable balloon cuff around the outer cannula that creates a seal within the trachea when inflated. This seal serves multiple purposes: preventing aspiration of secretions or gastric contents, enabling effective positive pressure ventilation, and facilitating accurate measurement of exhaled gases. The cuff pressure must be carefully monitored and maintained between 20-25 cmH2O to ensure adequate seal while preventing tracheal damage. Cuffed tubes are essential for patients requiring mechanical ventilation or those at high risk for aspiration. The cuff can be deflated to allow speech or swallowing assessment when clinically appropriate.
Usage
Usage note: Distinguish from uncuffed tubes used for patients not requiring mechanical ventilation.
