Air Fx – Caloric Air Irrigator for Vestibular Testing (Interacoustics)
Air Fx is a high-precision caloric air irrigator system developed by Interacoustics for advanced vestibular and balance assessments. It is widely used in clinical audiology and neuro-otology to evaluate the function of the horizontal semicircular canals in the inner ear through caloric testing.
The system delivers carefully controlled warm or cool air into the external ear canal to stimulate the vestibular system. This controlled thermal stimulation allows clinicians to assess balance function and identify possible vestibular disorders such as vertigo, dizziness, and other balance-related conditions.
Air Fx is engineered to ensure accurate, stable, and repeatable stimulation, making it highly reliable for detailed diagnostic evaluation of bilateral inner ear function.
Air Fx works by introducing controlled temperature changes in the ear canal. This thermal variation creates fluid movement in the inner ear, triggering nystagmus (involuntary eye movements). These responses are recorded and analyzed to assess vestibular system function.
