Project Description


The KayPENTAX Phonatory Aerodynamic System (PAS) offers a complete system for measuring key aerodynamic and intraoral pressure parameters during phonation. These measurements include average phonatory flow rate, subglottal pressure (derived), laryngeal resistance, and voice efficiency. Protocol-driven software allows clinicians to administer tasks and make key airflow measurements easily. Available built-in normative data provides a reference point for interpreting patient data. In addition, concurrent capture and display of EGG data (EGG not included) provides information on vocal fold dynamics.

Aerodynamic and intraoral pressure measurements are used in combination with acoustic and stroboscopic assessment in leading voice labs.
