this will get me flamed

yep it would be intresing to find out as that would explain a lot of people who dive for years then start to get unexpland bends,
are we seeing you and hubby at the gig tomorrow?


I dunno, I'm very keen to see if DrMike can dig anything up regarding his last post....[/quote]

Sorry, neither of us are fit to dive this week! I was just short of a buddy (Mark is taking a month or so off, and Leigh is also taking some time out) and an old neck injury of mine has decided to rear its ugly head....

only time will now tell lou and i just hope i can get sorted out ??? i cant try to forward see to the test ?that will get me to a place where i know i can either stop or see how i can get the op done ???? and then figure is it all worth it ?as my body at the moment after 3 bends in as many months is just not on and feels like ive been kicked up and down ??so no more diving for me ???not yet anyway

Sorry, took me a while to recall where Id read it.


The info came from Dr Marvin Gozum of 'Primary Care Diving Medicine' in a post he put up, Ive highlighted the bit about PFO in blue and included the rest as it is quite interesting.

"Most (90%+) of unexpected [i.e., the older term is undeserved] hits from recreational diving recover completely right after recompression treatment. These 'hits' are mostly DCI2. This is typically were the suspicion of PFOs come from, why did they get DCI2 if they executed the dive properly? While many have PFOs, many also do not, suggesting shunting of a different type. For those with residual symptoms, nearly all recover a few days afterwards and there are ~ no deaths due to unexpected DCI [not unless they have a heart attack from having a bad heart in the first place, and even then its rare.]

These risks have to be compared against a small risk of death simply to diagnose a PFO via a TEE and later from the surgery to repair it. Then, there are the potential complications from the procedure not working out. Unlike other tests, the diagnosis and treatment of a PFO is done by a specially trained cardiologist, not just a regular cardiologist.

All sport divers pass the basic recreational diving phase of their careers, often performing heinous errors of diving practice. If something were to happen, it often happens during this time. Thus its critical to pass this phase not just for skills and experience, but to determine any physical, mental or medial issues that would preclude advanced level diving.

It is possible that the tissue around the PFO may weakend as a diver ages, causing it to open wider later in life. It won't happen to all PFO patient's though. So a PFO silent or even undetected after many years, may show itself after a diver has been diving well for years. Then we have a rare event when an experienced diver gets a unexpected hit on a weenie or recreational dive.

Dr. Thomas case, detailed on scubaboard.com, is an extreme case. He provides testimony and detailed records, including his computer dive profiles. There are no errors in his dive profile or gases, at least by his report. After 400+ dives, he later finds a PFO.

A common clue to a possible PFO or other shunts in no stop dives executed properly, done without coexisting issues such as contaminated gas, c02 build up or malfunctioning gear, are:

unexplained post dive headaches;
unexplained subtle abnormalities in a neurologic exam;

Finally, despite the absence of screening for PFO among divers and its supposed high incidence, millions of dives are done annually, yet the number of unexpected hits among experienced divers is very rare.

Until the benefit/risk of a TEE is less than getting an unexpected hit, the diagnosis and treatment may harm more divers that the disease itself"

cheers for that mike a very intresting point indeed !!!! although saying that after the first time i had a dci (bend) of which it definatly was!! the 2nd and 3rd time in the chamber was instigated with symptoms no more than tiredness and dizzy spells which in all honesty could be related to something else ie inner ear infections ? of which the specialist from the chamber said it could be, cos i was unsteady on my feet and told him of past problems with quite severe cases of ottitus externa ,where i have had to use spray antibioics to sort out the problem so to some it all up maybe there is a potential of the first bend i had praying on the back of my mind and being a little jumpy at the sign of symptoms ?i hope that makes sense ps thanx for finding us the link out its much appreciated mate
