  • During the examination, silence is required, the examinee cannot chew or swallow, and has his eyes closed to reduce visual stimuli.
  • In young children, the examination is usually performed after feeding, while the child is asleep:
    1) In the nighttime hours or early in the morning before the examination (before the traditional hour of getting up), it is necessary to wake the child and not allow him/her to fall asleep again until arriving at the laboratory so that at the hour of examination the child is sleepy and tired.
    Take care that the child does not fall asleep during the journey!
    2) The child should be lightly hungry on arrival at the examination, e.g. the child eats the last meal in the evening and then only in the morning at the laboratory before falling asleep.
    Feeding the child just before the examination increases the child's chances of falling asleep faster.

Description of the study

The test evaluates the functioning of the auditory pathway down to the level of the brainstem by assessing the V-wave (significant for the proper functioning of the auditory pathway).
Three electrodes are placed on the patient's head - an active electrode on the forehead, two electrodes on the mastoid process of both ears. Earphones are placed in the ear canals to emit a crackle or tone. A computer records the responses, averaging the electrical potential values, and records the results.
