I am competing to be the world's most conservative
diver. About six years ago, diving on the Hilma Hooker,
where it's impossible to go deeper than 100 feet, a
good friend incurred a serious neurological hit. He
became paralyzed from the waist down, incontinent of
the bladder, extremely dizzy from a bubble in his inner
ear/balance organs and was nauseous and vomiting. It
proved to be multiple neurologic hits from arterial gas
embolizations. He stayed a week in Bonaire for multiple
chamber rides at the excellent chamber facility.
Later, it was discovered he had a large PFO [Patent
Foremen Ovale - hole in the heart] that our cardiology
group plugged with an "Amplatzer Occluder." Hemade
a complete recovery and was cleared to return to diving.
I was with him on that dive six years ago, diving
the same profile. We went briefly to a little less than
100 feet and slowly rose to the surface with a safety
stop. Our computers verify this. Since then, as a DAN
bubble study test subject, I learned I do not have a PFO.
Microbubbles formed in my venous blood, but that's
common, even when diving within the acceptable depth
and time limits, and not dangerous unless you have a
PFO.
Regardless, because of my buddy's experience, I am
now officially a conservative diver.
