Hi Folks,the blood vessels eg capilliaries in the nose and mucous membranes are very fine and easily damaged.(Think of when you blow your nose frquently with a cold).A reason why John may have experienced nose bleeds when flying but not diving is probably due to the moisture present/humidity etc.It's well known that "dry" equalisations eg in a chamber,can cause people difficulties when normally they would'nt encounter any in the water.This is why many Commercial divers use olive oil on their ears in a chamber,to allieviate the symptoms.Possibly John's nose bleeds are related to this,after all the pressure changes are there,just the water's missing.Hope this helps,Hobby. |
