Aerodynamic characteristics of Blom-Singer low-pressure voice prostheses.
In vitro airflow resistance calculations were completed for 20 low-pressure voice prostheses (Blom-Singer). Total device resistances ranged from 63.51 to 105.91 cm H2O per liter per second (LPS), with an overall average resistance of 82.04 cm H2O/LPS. Resistance characteristics were compared with those of other commercially available devices.
