What is it indicated for?

The Eustachi is indicated for the treatment of negative middle ear pressure.

Negative middle ear pressure can lead to fluid accumulation in the middle ear, impaired hearing, and hearing loss. The Eustachi provides a method of ventilating the middle ear by momentarily increasing the air pressure in the nose and the eustachian tube. Equalizing the pressure can prevent the accumulation of fluid and prevent hearing loss.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
