1.2 Intended use

The Aqua Stim caloric irrigator is used for stimulating the motion sensors in the ear using warm or cool water
pumped into the external ear canal. This standard clinical test is used to determine if the motion sensors are
working properly in patients with dizziness or balance problems. Typically, four irrigations are performed, a
cool and a warm for each ear. Responses to the irrigation are then compared to determine if one ear motion
sensor is weaker than the other ear sensor.
The Aqua Stim can be used in conjunction with the Interacoustics VN415, VO425, VisualEyes 515, and
VisualEyes 525 VNG/ENG software and Micromedical Spectrum VNG via USB. When integrated with one of
the aforementioned software programs, use of the Aqua Stim irrigator will start the caloric test with the
correct irrigation temperature.
All personnel who operate the Aqua Stim should familiarize themselves with the contents of this manual prior
to using the irrigator with a patient. Additional training can be requested via Interacoustics or one of its
representatives.
Aqua Stim should be used for irrigating the external ear canal only for the purposes of caloric stimulation as
a part of VNG/ENG test protocol. The device is not intended for clearing ear wax.
If service is required, please contact Interacoustics or the local Interacoustics distributor.
The intended use of this product is for irrigation of the patient's external auditory canal with either warm or
cool water for the purpose of assessing the peripheral vestibular system. The product is intended to be used
by a trained professional in a clinic, hospital, or rehab setting. The appropriate patient population includes
children and adults with normal external auditory canal and middle ear anatomy.
Contraindication:
Do not perform irrigation on patients with tympanic membrane perforations.
