7.3 Goggles placement
When goggles are placed properly they sit comfortably on the bridge of the nose and will not slip during the test.
Caution• Goggles fit is Important. Improper goggles fit can result in inaccurate data collection. Goggles slippage
often results in inaccurate gain values (too high).
Note• You can find more information in the ICS Impulse training video or at www.icsimpulse.com.
After placing the goggles on the patient and tightening the strap, look at how the goggles fit on the person's face. If there
are gaps between the goggles and the patient's face the goggles may slip.
Improper goggles fit
1. Before putting the goggles on the patient ensure
– the goggles have a new unused face cushion. Refer to Goggles preparation ► 16.
– the mirror is clean. Refer to Cleaning and maintenance ► 16.
Note• The single-use, disposable face cushion must be replaced for each new patient.
Caution• Improper cleaning may scratch the mirror surfaces.
2. If required, replace the strap. Refer to Cleaning and maintenance ► 16.
3. Position the goggles on the patient’s face over the bridge of the nose.
4. Bring the strap above the patient’s ears and around to the back of head.
5. Tighten the strap tight enough to ensure that goggles will not shift during testing.
