I participated in the clinical trial at Duke that's linked to from that story, which honestly was a blast. That the medics let this guy keep training is astonishing to me. If they measured his pulse ox and sent him back in anyways, that's criminal. Also, as I understand it, Sildenafil during dives is a bad idea (something about seizures) which might be why it's "banned" in SEAL training.

But who funded the Duke study that surfaced Sildenafil as a candidate drug? The Navy SEALs, of course.
