what the risks are caloric test, caloric stimulation, test which uses differences in temperature to diagnose ear nerve damage, a cause of dizziness, vertigo, vestibular portion, the nerve, the inner ear, acoustic nerve, common cause of vertigo, each ear is tested separately using a computerized caloric stimulation machine, nystagmus, quick movement of both eyes in response to certain stimuli, is necessary, normal vision, balance, measured using electrodes around the eye, recorded, analysis by the computer, cold water, in the ear canal, a bulb syringe, should cause nystagmus, test is then repeated using warm water, nystagmus should occur, in the opposite direction, towards the warm water then slowly away, rather than away, water, slowly back, computer analyzes, cold, warm water response, each ear, differences between ears, differences between cold, warm water responses, warm, cold air, hole, in the ear drum, ice cold water, in absence of any response, avoid eating a heavy meal, avoid caffeine, alcohol, allergy medications, sedatives at least 24 hours, affect the results, ask, written instructions from doctor, infants, children, test depends on child's age, level of trust, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, there is minimal discomfort, find cold water, in the ear uncomfortable, brief, severe vertigo, caloric stimulation is performed to evaluate the acoustic nerve, provides hearing, helps, balance, test recommended, someone is experiencing dizziness, vertigo, hearing loss, suspected toxicity from certain antibiotics, anemias, psychological causes, vertigo, suspected, the presence, extent of brain damage, comatose person, nystagmus should occur after instillation of cold, warm water, ear, nystagmus, similar on both sides, nystagmus, does not occur after cold, warm water is instilled, difference, the responses of each ear, between cold, warm water response, some damage, nerve, the inner ear, controls balance, nystagmus, does not occur after ice cold water is instilled, permanent damage, nerve has probably occurred, injury that damages the acoustic nerve, cause vertigo, congenital disorders, present at birth, trauma, rubella, blood vessel disorders, hemorrhage, bleeding, clots, atherosclerosis, the blood supply, the ear, cholesteatoma, ear tumors, poisons, ototoxic, toxic, ear nerves, medications, aminoglycoside antibiotics, antimalarial drugs, loop diuretics, salicylates, additional conditions, which the test performed, acoustic neuroma, benign positional vertigo, labyrinthitis, meniere's disease, excessive water pressure, injure a previously damaged eardrum, rarely occurs, water to be used is measured in advance, caloric stimulation should not be performed eardrum is perforated, the risk of causing ear infection, caloric testing should not be performed, an acute vertigo episode, make symptoms worse, caloric stimulation is approximately 80% accurate in differentiating nerve damage, a cause of vertigo, tests required to confirm the diagnosis.
