Vng virus protection

During this part of the VNG, you will watch and follow moving and nonmoving dots on a light bar. Positional testing. During this part, your provider will move your head and body in different positions. Your provider will check if this movement causes nystagmus. Caloric testing.

During this part, warm and cool water or air will be put in each ear. When cold water or air enters the inner ear, it should cause nystagmus. The eyes should then move away from the cold water in that ear and slowly back. When warm water or air is put in the ear, the eyes should move slowly toward that ear and slowly back.

If the eyes don't respond in these ways, it may mean there is damage to the nerves of the inner ear. Your provider will also check to see if one ear responds differently from the other. If one ear is damaged, the response will be weaker than the other, or there may be no response at all.

Will I need to do anything to prepare for a VNG? Are there any risks to a VNG? What do the results mean? If the results were not normal, it may mean you have a disorder of the inner ear. These include: Meniere's disease , a disorder that causes dizziness, bouts of hearing loss, and tinnitus ringing in the ears.

It usually affects only one ear. Labyrinthitis, a disorder that causes vertigo and imbalance. It is caused when part of the inner ear becomes infected or swollen.

The disorder sometimes goes away on its own, but you may be prescribed antibiotics if you are diagnosed with an infection. If you have questions about your results, talk to your health care provider. Is there anything else I need to know about a VNG?
