Page 6: Candidacy
Candidacy Nucleus Hybrid mode is suitable for recipients who satisfy audiometric and hearing performance criteria post-operatively, and have appropriate expectations regarding outcomes. New CI recipients: Post-operative evaluation Perform unaided post-operative audiometric testing of each ear at regular intervals, to monitor residual hearing levels over time. This should include air and bone conduction thresholds and tympanometry as indicated, to detect the presence of any temporary or permanent conductive component. -
Page 7: Existing Users: Upgrading From Older Processors
Existing CI recipients, or those using Hybrid mode on older sound processors, can be converted to the Nucleus 7 system with Hybrid mode. To do this, you need to fit them with a Nucleus 7 Sound Processor and Cochlear Hybrid receiver and dome, and reprogram their system with Custom Sound software Version 5.0 (or above). -

Page 16: Program Hybrid Mode
The options for Hybrid mode are: • CHP: Cochlear Hybrid Prescription. By default, CHP with WDRC (Wide Dynamic Range Compression) is selected. It can be used with or without compression in Hybrid mode. • NAL-RP: National Acoustic Laboratory. Revision for profound losses prescriptions that equalise prescribed gain to make each frequency band of speech of equal loudness to maximize speech intelligibility. -

Page 24: Shape The Hybrid Receiver Cable
Shape the Hybrid receiver cable Problem: Hybrid receiver cable is between sizes – too long or too short. Solution: To improve fitting comfort and retention, the Hybrid receiver cable is heat formable. This allows for variations in ear anatomy and for those recipients whose measurements fall between two lengths. -
Page 25: Managing Occlusion
Managing occlusion Occlusion is often described by the patient as: • sounding like their head is inside a bucket • sounding like they are speaking into a tunnel • having a bad perception of their own voice • feeling like acoustic stimulation is becoming unbearable. NOTE An initial feeling of occlusion may occur when the system is first fitted or the program is changed. -
Page 26: Service
If the Hybrid earhook, receiver or dome breaks or is lost or damaged, you can replace it from your existing stock or order it from Cochlear. If an earmould is damaged, fit a dome if possible and order a new or replacement earmould. -
Page 27: Warnings
• Counsel carers to routinely check the Hybrid system by turning on the sound processor and listening closely to the Hybrid system. Where available carers should be advised to use the Cochlear EAC200 Series Stetoclip. • If you fit earmoulds, only use them with the 60 or 85 size Hybrid receivers. Do not use custom earmoulds for any larger size receivers. -
