It's a lot more involved than CPAP. You need to have a low enough BMI to qualify which excludes a not insignificant proportion of apnea patients. You need to have predominately obstructive sleep apnea since the device can't treat central apneas (where you just stop attempting to breathe). You need to be fit enough to tolerate surgery. You usually need to have an induced sleep study where you get put to sleep with propofol while someone uses a nasal endoscope to watch what part of your airway becomes occluded when you sleep to see if it's even something that can be treated with the device. And then even after all that the device essentially zaps your tongue to make it move and open your airway and for some people they find this intolerable, and the device needs to be turned off. After all that I think it's effective in about 50% of people.

So given all of that, I think it's better to work on trying different masks and other strategies for getting used to the mask before considering the implant.
