If AutoPower > 75%, battery life will be short

Potential for intermittency

Do not mix brands of batteries

Sounds constantly unpleasant

Sound is fuzzy, off stationor buzzing

If intermittent buzzing may be EMI

Patient showing signs of distress/ discomfort

Decrease in listening ability

Banging/ crashing sounds Possibly faulty electrode(s)


44/48

Issues to remember

Know your serial numbers.

Note the Colour and Size of the cables for easy

reference.

Use the Dry Aid Kit every night.

Minimize the chances that the cables are pulled/ stretched.

Careful with that ear hook.


45/48

Issues to remember

Avoid sand/ dirt

Clean with slightly damp cloth

Keep dry + use dry pack provided

Avoid sources of ESD Plastic slides, Balloons

Computer/ TV screens

Avoid medical treatments inducing currents Diathermy or neurostimulation

Electroconvulsive Therapy

Monopolar electrosurgical instruments must NOTbe used on the head or neck of a CIuser. Use

Bipolar electrosurgical instruments instead. Do not use Ionizing Radiation therapy directly over

CI


46/48

Issues to remember (cont.)

Consult Implant Centre/ Cochlear before MRI

Always use processor with Cochlear approved

ALD devices and accessories

CI Recipient should carry Patient ID card

Theft/ Metal Detection Systems Air Travel


47/48

MRI scan for Nucleus Cochlear Implant Recipients

MRI safe at 0.2T with magnet

MRI safe at 1.5T with magnet (with precautions)

MRI at 3.0Twill

require removal of the magnet

Nucleus 24 first with a removable

magnet, approved* to 1.5T since 1998
