Abstract

• Airway resistance calculations were completed for two tracheoesophageal puncture prostheses (American V. Mueller Blom-Singer Voice Prosthesis and BIVONA Low Resistance Voice Prosthesis), which have recently become available on a commercial basis. These calculations were compared with those made previously for two, existing prostheses: the Blom-Singer duckbill and the Panje Voice Button. Substantial differences in airway resistance properties exist among these four devices. BIVONA Low Resistance devices exhibited the lowest resistance (<50 cm H2O/liters per second [LPS]); Panje Voice Buttons exhibited the highest (180 to 200 cm H2O/LPS); and BlomSinger devices exhibited intermediate values (110 to 125 cm H2O/LPS) of opposition.
