So I found this to be interesting. In the IDES process I was diagnosed with sleep aphnea, requiring a pressure of 13 psi. When the lady delivered my machine, she pointed out that it had an SD card, and that the VA would be downloading these cards in the future to verify that people are using the machines in order to maintain the disability benifits. I use mine and it has improved my AHI dramaticlly, but after talking to my neurologist who administers the sleep studies I got the impression there is alot of pushback from the VA on all the SA cases they are seeing, so they are being alot more reluctant to give this diagnosis. This is at NAS Jax, but I imagine it will spread to other facilities as well.
