Q

programming software for AB

A
  • soundWave
  • attaches CIs with clinician’s programming interface-3 (aka CPI 3)
  • can connect CIs to allow for bilateral programming
  • as soon as you connect to SoundWave it will run impedance testing automatically
  • –has option for monopolar coupling

Q

conditioning

A

after non-use especially

  • is sending a burst of current through the cochlea and is helpful for measuring impedance during surgery when in use for the 1st time and turning an electrode back on after it has been off
  • –the current is to get rid of air bubbles and break off buildup before stimulation

Q

AB coding strategies

A

HiRes-P, HiRes-S, HiRes-P Fidelity 120, HiRes Optima-P and HiRes Optima-S

  • HiRes Optima S is the recommended coding strategy, but he others are available for older devices
  • –C1.2 devices use CIS, MSP, or SAS

Q

ClearVoice

A

feature to help with attenuating noise by monitoring different channels and seeing what is noise and what is speech, reduces amplification in the channels with mostly noise
*can sit it to low (6dB), medium (12), or high (18) which means how much attenuation to the channels with the noise

Q

stimulation level for AB is measured in ____

A

charge units(CU) which is widthamplitude0.013

  • –basically if trying to increase intensity, then amplitude will increase until it cant anymore and after that the width will start getting larger and larger
  • –this process is automatic
  • 0-6,000 CU but rarely if ever go near that high

Q

adjusting rate with AB

A

not something that can be controlled in the software directly, must be done by adjusting the width of the pulse

  • –AWPI is automatic pulse width I and AWPII is automatic pulse width 2, can also manually change the rate
  • —->/= 37.7 micro seconds which results in 1768 pps
  • ——-will get a warning when out of compliance

Q

T-level for AB

A
  • recommended to be estimated at 0 of 10% of the M-level to be sure threshold is not audible to pt because internal noise can be heard with CIS coding strategies
  • –want to really measure threshold only if the pt is not progressing or performing as well as they should , then take threshold (audible 50% of the time) and reduce by 10-15 CU to make sure to set the threshold a little below what it really is

Q

M-level for AB

A
  • can be set by tone, speech burst, or live speech stimulus
  • –measuring with tones would be mapping 1 electrode at a time
  • –measuring with speech burst would be mapping 4 at a time
  • –measuring with live speech would be controlling all electrodes together=global changes
  • can also be measured at or a little below ESRT (if below then go within 5-10% of the ESRT)

Q

VC with AB

A

minimum and maximum is how much in percent of dynamic range the pt can increase or decrease the M-level

  • dont want to give them too much for the + because we dont want them to set the M-level too high
  • default is +20% and -50%
  • –generally +/-20% is appropriate for adults

Q

input dynamic range with AB

A
  • aka IDR
  • default is 60dB (20-80)
  • this is not saying that it is from 20 dB SPL to 80 dB SPL but is saying that the range can be as small as 20dB and generally up to 80dB
  • this is really how much access you want to give your patient to low level signals (we would want wide for quiet or music and smaller for loud sound environments)

Q

audio mixing ratio (AB)

is for using accessory and mic, is how much input you want from mics vs accessory such as FM

Q

AGC-II (AB)

A

is dual loop meaning after it hits the 1st knee point it is slow acting and then it is fast acting after the 2nd kneepoint

  • –slow kneepoint is 63 dB and fast is 72 dB
  • –could also do linear and the kneepoint would be 65 dB SPL

Q

ground electrode (AB)

A
  • the electrode on the casing is the default
  • dont mess with this unless there is a problem with this one, then can switch to the ring electrode (ex of problem would be faulty case or facial stimulation)

Q

HiBAN (AB)

Study These Flashcards
A

hearing instruments body area network technology

  • using a high frequency wireless connection and use compilot or connection between Naida CI and Naida Link
  • digital inductive 10.6MHz technology
  • delivers signals and control over short distance (MP3, phone) using the compilot
