gosh you are a bit paranoid aren't you? since when was there an NHS in South Korea?
If you've ordered a fixed pressure CPAP then you've probably wasted your money as it's difficult to manually titrate unless you know what you are doing and is not much good without a prescribed pressure. If you've ordered an auto then it's not so bad. It would be much more ideal for you to have someone checking on you to ensure you are getting optimal treatment. a certain manufacturer I'm not going to advertise (makes the machine you ordered
) runs a private service where you can send them the data from your machine and someone checks it for you. Disclaimer: Other companies exist and offer a similar service and I'm not endorsing any of them including the above ) If you were in the uk I'd definitely say you'd do better with the NHS but I don't know what the health care system is like where you are. Using an APAP without a sleep study is not a problem in itself. Some major sleep centres go straight to a trial of APAP in those with highly suggestive histories of OSA, but they are then monitored by highly specialist physiologists, nurses or physiotherapists, with access to a consultant. Their GP will also have taken a detailed history and checked for a number of potential other problems. You should therefore make sure you get yourself medically checked out and monitored on your CPAP. also CPAP is more difficult after surgery (I assume you've had a UPPP) for instance you are unlikely to get on with a nasal mask. Another reason for seeing someone and not just self treating.
