I have been dealing with sleep apnea for about nine years....a full year undiagnosed, at least, and now eight years using a PAP device nightly. I have also spent a lot of time reading up on sleep apnea and am a member /advisor over on apneaboard.com forum. The advisor is not meant to mean I'm really up on the topic and able to give advise...it means I advise the forum staff on matters that might make members' experience and success greater if we change X and not Y. So, NOT an ex-spurt.

There are many bright ideas. Some work, despite being intuitively brilliant or because of it. And vice versa. The Inspire product has mixed reviews. Some swear by it, others say don't waste your dough. It's one of those things many choose because they can't adapt to a PAP machine and its delivery system. It doesn't help much, but it may help....some....to open the airway, which is really the problem all but 'central sleep apnea' patients suffer from. There are three types of sleep apnea: obstructive (90% of all patients formally diagnosed), central (which is a brain condition), and 'complex' apnea with is a dreadful combination of the two. Central sleep apnea is most often successfully treated with therapy provided by expensive machines called 'adaptive servo-ventilators.' Obstructive apnea is treated with straight PAP pressure or with adjustable/bi-PAP machines, depending on the user's individual needs. Pressure therapy works. The Inspire product is meant to 'stimulate

This is a cut 'n paste from 'sleepfoundation's' website:

A clinical study found that after 12 months of using the Inspire device, 66% of study participants

cut their AHI scores by at least 50%. The study also determined that 75% of participants had at least a 25% reduction in oxygen desaturation index (ODI), which measures how frequently a person’s blood oxygen level dips below normal for 10 seconds or longer. The median AHI score decreased by 68%, while the median ODI score fell 70%

So, you'd want to be a 'reject' from PAP therapy, a concerted college try, and you'd want to bear the expense and relative permanency of an implanted device that electrically stimulates tissues in your tongue and throat.
