Performing Eustachian Tube Function (ETF) Test: a Guide to Controls and Settings

The Eustachian Tube Function (ETF) test is designed to assess the efficiency of the Eustachian tube under different physiological and pathological conditions. In Inventis instruments, the test is available in two modes: with intact tympanic membrane and with perforated tympanic membrane. Each mode provides specific interfaces and configurable parameters, enabling the operator to adapt the procedure to the patient’s clinical needs. 
This Product Insight outlines the key controls, settings, and screen layouts required to conduct both types of ETF tests effectively, offering a practical guide for daily use.
