Jim, I sent that info to the parents so they can inquire with the doctor, from my point of view it doesn't match real close with his condition, his blood pressure was spiking at 190 on the way to the hospital.
As to did we check about an AED before the dive, we did not, if they have one there I would hope they would know how to use it, within 5 minutes of me requesting air someone had it there and hooked up quickly for us. I've learned a lot from this incident and I appreciate the input people have given.
Just to point out how fortunate we were, that was our second dive of the day, my Dad passed on the first dive because he didn't feel comfortable about the entry, this site was just south of the Hilma Hooker, no dive shop, oxygen, phone, people to help carry him, and we didn't know where the hospital was. Needleess to say we're all glad he passed on the dive.

Here is some feedback I received from my parents:
"Hmmm interesting. Im still leaning on the Immersion Pulmonary Edema guess at this point from the folks at Dan
it seems the most plausible given the situation and the fact that they could not find any other issues with him once at the hospital. The Dan person also said that unless they would have done a CT scan of his lungs/chest almost immediately after arriving at the hospital we may never know. Although not all symptoms are completely identical to Bills this is interesting from Scuba Board as well

From my perspective, this sounds like a very good possibility.
