Hey Everyone,
Vertigo is the feeling that the world around you is moving, spinning or tilting while you are remaining essentially still. Vertigo can be a result of a number of ailments, ranging from an infection in the inner ear to chronic problems such as Meniere’s disease.
Vertigo is not
uncommon among divers, and your experience with it occurring when you are at
significant depth is fairly typical. Diving physics tells us that the greatest
pressure changes occur closer to the surface, but as the diver descends
, equalizing the pressure in the middle ear is still very
important. Divers generally continue to descend even when having
difficulty with equalizing. Plus, the middle ears need to equalize during
ascent as well.
You are experiencing alternobaric vertigo, which is caused by unequal
pressures between your middle-ear compartments. The pressure diference does not
have to be very great. The inequality is communicated to the inner ear organs,
resulting in vertigo.
Divers can
also experience nausea and vomiting. Vertigo is usually more common while a
diver ascends. Not only are the symptoms uncomfortable, but they also can lead
to catastrophic problems for the diver. Vertigo can also occur when diving
with a hood if one side of the hood seals over the ear tighter than the other.
Prevention of
vertigo during diving requires careful, gradual and continuous equalization of
the pressures within the middle ear throughout the dive.
Remember to avoid vertigo do not dive when feeling sick or
congested or immediately after an upper respiratory tract infection or cold.
Never force air into the ears
I think i have this problem. I always thought it was me alone with this and i was feeling sick. Now I know what the cause is.
