Getting the CPAP Machine req removed from DOT Physicals

I have a trucker friend who has sleep apnea. His DOT Physical says that he has sleep apnea, and he has to use a CPAP machine to be compliant. If my trucker friend with sleep apnea goes to another trucking company and gets a new DOT Physical with the doctors at his new trucking company, and if he tells the doctors at his new trucking company that he has never had sleep apnea, can he get a new DOT Physical and medical card that does not require him to use a CPAP machine any more? Or will the new doctors know that his last DOT PHysical said that he has sleep apnea and must use a CPAP machine, making it so that he will still be required to use a CPAP machine even if he tells the medical examiners/doctors that he has never had sleep apnea? I'm asking for a friend.

 

So the doctors/medical examiners will have access to his previous DOT Physical?

 

How would the doctors/medical examiners at a new doctor's office be able to access his previous DOT Physical? Is that all computerized and put on the internet now or what?

 

I don't know what this post means. The DOT doctor will send them back for a re-test if he's anywhere near close to what?

 

The medical examiners won't approve my friend's medical card unless his pulmonologist faxes a letter to the medical examiners telling them that my friend is in compliance with the CPAP Machine rules and is safe to drive. My friend is worried that his pulmonologist will say "I don't have time to fax the medical examiners to tell them you're in compliance" and refuse to send the fax.
