Six tips for successful immittance testing in a busy clinic

  1. Size matters! The correct size probe tip is important to achieving a reliable seal. And it can be difficult to estimate what size ear tip to use. So if you have trouble getting the seal on the first or second attempt, go up one or two sizes until you find the size that fits your patient’s ear.

  2. Make sure the probe tip fits securely on the probe. After selecting the ear tip, firmly push and twist the ear tip onto the probe tip until it rests firmly against the base of the probe tip.

  3. Look first. Ensure you have a good view of the ear canal before you place the probe. Grasp the pinna and gently pull the pinna back and slightly away from the patient's head. This opens the ear canal so you can see the opening and makes it easier to place the probe correctly in the ear canal. 

  4. Place the probe securely in the ear canal. Press the probe against the patient's ear canal so that an airtight seal is achieved. It may help to gently push or twist the probe for firm and accurate placement. 

  5. Silence is golden. Ask your patient to remain completely still and silent during the test. This can be difficult with children. Therefore, make sure the child is situated where they feel comfortable and safe before testing.

  6. Know your colors. Before testing your patient, be sure to familiarize yourself with the color signals from the lighted probe tip and shoulder pad. (See the chart below.) Note that the color pink means the probe tip is occluded or is angled incorrectly and touching the sides of the ear canal. You can also get the pink light if you touch the probe tip with your fingertip. Also, during the test, pay attention to the probe light – not the light on the shoulder pad.
