What tests can be performed with the GSI Allegro?
The Allegro conducts middle ear screenings on a variety of patients. The device can perform tympanometry using a 226 Hz probe tone and ipsilateral acoustic reflex testing at 500, 1000, 2000, and 4000 Hz from 70 - 100 dB HL.
What middle ear measurements are displayed?
The Allegro displays four measurements. Automatic tympanic admittance peak, peak pressure, ear canal volume, and gradient are included.
What is the ear seal check?
The ear seal check ensures that adequate pressure can be created in the ear canal prior to performing middle ear testing. If a seal is obtained, the tympanogram will automatically be measured.
What settings can be customized on the Allegro?
Allegro makes it easy to customize settings for each patient. There are 17 settings the user can easily change. For example, the reflex frequencies, intensity step size, and intensity levels may be specified by the user.
Do I have to clean the probe tip on the Allegro?
Yes, cleaning the tip is necessary. The probe tip should be inspected every time prior to placing an ear tip. The small holes through the probe tip must be kept clear. If debris or blockage is visible, the probe tip must be removed from the unit and cleaned using a floss cleaning kit. It may be necessary to replace the probe tip if damage is visible.
