I wonder if it would be helpful to allow people who experience sleep issues to just get a CPAP machine and try it out, instead of having to go through a sleep study.
So may people find their CPAP uncomfortable when they first use it, that it's unlikely they'll use it properly. Having a first use under the watchful eyes of a physician could be a good idea.
Then again, some people also get one and then don't use it, so maybe it's more of the same.
Also, a doctor can show you how to use one, you would not necessarily be completely on your own.
Sleep studies are just such a hassle (and expensive, depending on where you live), and if you have a weird sleep schedule it can be difficult to even fall asleep in time.
Being able to just rent a CPAP machine for a couple of days and have a doctor show you how to use it would be a good option to have.
Any recommendation?
