All is perfect and I am sleeping like a baby. I also have energy all day long! Best decision I ever made. If anyone has questions, please feel to contact me or ask questions here.
I have a few questions.
1) I understand there is a pacemaker-type device that sends the currents up the wire to stimulate the throat muscles. Is this device implanted under the skin? What does it use for a power supply and how long does it last?
2) What happened during the six month study? Were you monitored like in a sleep lab? Every night, or periodically, or how often?
3) Do you recall how severe your sleep apnea was before the procedure, like AHI numbers from previous sleep studies? And do you have numbers for what it is now after the procedure?
Thanks for posting about your experience. I know a lot of people are interested in the APNEX device.
The pacemaker like device is implanted just under the collar bone on my right side. I know one of the fellows in my study group had it put on the left side so he could still hunt. I have a lead that goes to my diaphragm and one to the HP nerve in my jaw. The device has a battery that is changed about every 5 years. Implant was simple. I had it Friday and was back to work on Tuesday. Only a little discomfort after implant. I am not aware of it at all now.
I was monitored via 3 or 4 sleep studies over 6 months. I went in weekly for a download of the data in the device showing how well I was using it. Length every night, how many times I paused it and to move the titration up slowly. I started at .7 milliamperes and hit their goal of 1.6 after about 4 months.
I will look up my numbers but I can tell you that in initial sleep study I had 468 arousals over 6.5 hours. The three month study I was at 137 arousals over 7.5 hours. I do not have results from six month study but my guess is little to no arousals.
