A low-pressure cuff on a tracheostomy tube is in place to put less pressure on the tracheal structure, reducing the incidence of ulceration, while also providing a seal against air leaks during ventilation. The tracheostomy tube may contribute to friction and pressure against the structures of the trachea, which can result in tissue breakdown over time. A low-pressure cuff reduces this stress, but does not necessarily affect the vocal cords or speech.
