Voice intensity of patients using a communi-trach i® cuffed speaking tracheostomy tube

Abstract

Voice intensity levels produced by 20 patients with cuffed speaking tracheostomy tubes (Communi-Trach I®) at three different airflow rates were investigated. Results indicated that audible and intelligible speech was produced with significantly greater intensity over ambient room noise at 5 1/minute, 10 1/minute, and 15 1/minute of airflow. Criteria for use, common causes of malfunctioning, and rehabilitation techniques necessary for the successful use of cuffed speaking tracheostomy tubes are discussed. © The American Laryngological, Rhinological and Otological Society, Inc.
