A puzzling example of BO. There have been quite a few instances of BO or LMC among divers very young in the sport, reported on these forums. Most, if not all of them, were not practicing what many people think of as hyperventilation (huffing and puffing for extended periods) Likewise, I suspect that most were overbreathing, hyperventilation by the more stringent definition, just like a large number of other divers. Could be those early BOs are simply the result of hyperventilation. But, is it possible that some relatively small number of people are particularly susceptible to BO? Maybe overbreathing is more of a problem for them, or maybe there is some other factor involved hematacrit, blood chemisty? Anybody have any thoughts or evidence of this?
