NOTICE
The patient's perceived spinning sensation experienced during caloric irrigation is
the desired result of stimulating a functional ear with a caloric irrigator. The
clinician should remain at the patient's side to calm and reassure the patient that
the spinning will pass in a minute or so. Nausea is an undesirable side effect
which is temporary and not experienced by every patient. If the patient becomes
nauseated, discontinue testing until the nausea has passed. Be prepared to
provide the patient with an emesis basin. Stop all caloric testing for that visit if the
patient vomits.
3.7 Safety
The Air Fx air irrigator uses
distilled or demineralized water
to maintain the temperature in the cooler /
heater element. While the temperature of the coolant is not displayed, it is monitored. If the coolant
temperature goes over a certain limit, the unit will stop operation and an “Over Temp Error” message is
displayed. This error could be a result of insufficient water in the water reservoir or bubbles in the water
line. Operating the irrigator in very cold (<10°C conditions can also cause this error). Make sure the
irrigator has warmed up slowly to room temperature before operating.
Over Temp Error
Call TechSupport
The air delivery temperature is also monitored for safety. If this temperature exceeds 50°C, the irrigator
will stop operation and an “Air Temp Error” message will be displayed.
Air Temp Error
Call TechSupport
If either of these conditions occurs, then shut down the irrigator and isolate the problem (ambient
temperature too low, bubbles in the water line,
distilled or demineralized water
level too low etc. ).
Contact Interacoustics’ Service Department or the local service representative if the problem cannot be
resolved.
Set the Air Fx irrigator near the edge of the table or cart in order for the hose to hang down, allowing the
handle to rest properly in its cradle. When the irrigator is not in use, coil the Air Fx handle tubing using the
hose management tape while still allowing the handle to be secured in the cradle.
3.8 Turn off the irrigator
The Air Fx will go into standby mode after ten minutes has elapsed or the irrigation temperature selection
button is pressed twice. If the Air Fx is used in conjunction with the compatible VNG/ENG software, then
the software will send the Air Fx into standby mode at the end of the test. When the Air Fx is in the
standby mode, it is safe to turn off the power switch on the back panel.
3.9 Draining the water reservoir
The Air Fx should have the water reservoir on the top of the irrigator filled with
distilled or demineralized
water
. If the
distilled or demineralized water
needs to be drained prior to shipment or flushed before
adding new
distilled or demineralized water
, then the Air Fx should be drained according to the
following instructions. Do not store irrigator in a location below 0°C (32°F).
1. Remove the water reservoir cap on the top of the irrigator.
2. Connect the supplied plastic syringe and tubing to the Fill / Drain Water Outlet on the back of the
irrigator. Push the syringe plastic tubing fully into the Fill / Drain Water Outlet connector, and then
gently pull on the tubing to verify the connection is secure and will not leak.
3. Switch the Fill / Drain Valve to the Fill / Drain position.
