There are different machines ...
You may have a download card or memory card which may tell of your use
Your specific state and DOT and perhaps your company may have their own compliance requirements ...
It sounds from your question that you have required minimum 70 percent compliance ...
As the machines are smart these days I would advise that it is in your best interest to follow your guidelines for nightly treatment as best that you can !!
That would be safest for you I think !
I hope that this information is helpful for you
Let me know if you have further questions or concerns
I will be happy to get back with you
If you have specific info as to the CPAP machine I might be able to get you more specific information
If my answer has been helpful and to your satisfaction then please remember to leave positive feedback
Thank you and Best Regards,
Anthony Bray MD
