Totally understand no one here can clear him. Again if it's a definite no go then he doesn't want to waste time and money on Drs visits at this time.
He says he was treated for sleep apnea for 3 months prior to the PFTs and was/is 100% compliant. AHI was under 2 during that time but he thinks the hypoxia wasn't taken care of until after the PFT's. I guess he bought his own pulse oximeter and saw oxygen levels still dropping at night and then had a oximetry test done at home while using APAP and AHI that night was around 1 but oxygen was under 88% for 93 minutes.

Thanks, I'll let him know that and that he should make an appointment and that it's not a definite no go.

What I am kinda curious about is how low his residual volume is, if at depth would that further decrease it and if so could that cause any issues ?

Residual volume shouldn't change significantly while breathing compressed gas under water. That only comes into play with free divers.

Best regards,
DDM
 
Just thought I would update. He got kinda lucky , he was able to send a message to primary and not even have to go in and pay for appointment. Primary said he saw no contraindications other then possibly a fever that came and went everyday for 6 to 8 months that they never found cause for. The fever stopped after taking the synthroid for slightly underactive (just out of normal range) thyroid .
