I will definitely sign that letter, anything that I can help with really..
Wow, that's eye-opening! It's concerning how many people might be living with undiagnosed sleep apnea.
The process you described for getting a diagnosis and then finding more affordable CPAP options online is both enlightening and disheartening. It's unfortunate that cost can be a barrier to treatment for so many :(
Hopefully, with more awareness people can get treated and diagnosed properly
Using OSCAR is a great idea for digging into the advanced data in my opinion. Don't worry too much about understanding it all at once; it can be a learning curve.
Focusing on AHI is a good start. Feel free to share your stats after settling in with the device for a bit. Hoping it brings some positive changes to your sleep quality.
Remember, adjusting to CPAP might take time, so be patient with the process :)
