minimal leak technique

Abbreviation: MLT
A method of determining the appropriate cuff inflation volume on endotracheal tubes (ETT). The ETT cuff is inflated until no respiratory sounds are heard. The cuff is then deflated slightly until sounds are heard. Excessive cuff inflation volume may lead to necrosis of the trachea, and excessive leaking may render oxygenation and ventilation ineffective or allow aspiration of large particles from the oral cavity.
