*A head-spinning ear injury causes an
abandoned diver to lose his only route to survival.*

The pain in George's ear went from uncomfortable to
excruciating as
dizziness and nausea washed over him. The wide,
|
|
|
comfortable tunnel seemed to collapse in all around, and
his lungs tightened. Several deep breaths helped clear his
|
|
|
head and stave off the encroaching panic, but he knew he
could go no farther. He signaled his partners that he was |
|
|
turning the dive and beat a rapid retreat toward the exit,
which was only a few hundred feet away but still out-of- |
|
|
sight. Along the way,
vertigo struck with a vengeance, dizziness clouded his mind and he
lost contact with the
|
|
|
guideline--his only connection with the outside world. |
|
|
|
|
|
|
|
|
*The Divers* |
|
|
|
|
|
George was part of a three-man team of qualified cave
divers. All three were in their early 30s, in reasonably good
|
|
|
health and had experience diving these local caves. |
|
|
|
|
|
Each of the divers was properly equipped and certified to
dive this particular site.
|
|
|
|
|
|
|
|
|
*The Dive* |
|
|
|
|
|
The dive team planned for a maximum depth of slightly over
150 feet, penetrating the cave to between 2,000 and 3,000
|
|
|
feet depending on their air supply. The divers arrived
mid-morning, assembled their equipment and entered the water.
|
|
|
They were comfortable as they did their final equipment
checks and safety drills before dropping down and squeezing |
|
|
through the mouth of the cave. Visibility was good as they
tied off their line and swam down the dark tunnel.
|
|
|
Everything was going as planned until George felt the jab
of pain in his ear. |
|
|
|
|
|
|
|
|
*The Accident* |
|
|
|
|
|
Working his ear and clearing forcefully, George managed to
descend a few more feet, but the pain came back more |
|
|
intensely, along with a wave of nausea. He signaled to the
rest of his team, and they stopped the dive to give him a
|
|
|
chance to acclimate. As the problem got worse, George
decided to call the dive. He signaled his decision, waited for |
|
|
confirmation and turned around. George's buddies figured
he was close enough to the exit that they could continue
|
|
|
the dive without him. Heading back alone, George's
disorientation apparently intensified, and at some point, he lost
|
|
|
contact with the guideline. He probably swam frantically
searching for the exit or line because when his buddies
|
|
|
swam back through the area nearly two hours later, they
noticed extreme silting. They saw no signs of George,
|
|
|
however, and had no reason to believe he wasn't at the
surface waiting for them. After their decompression, the
|
|
|
divers climbed out of the water and were stunned to find
no sign of George or his gear--his car was still locked and
|
|
|
sitting where he left it. They notified local authorities
who organized a search and
rescue team. The searchers found
|
|
|
George wedged in a tiny alcove. His gear was out of place,
and there was very little air left in his cylinders. He
|
|
|
drowned trying to fight his way out--almost within sight
of the entrance. |
|
|
|
|
|
|
|
|
*Analysis* |
|
|
|
|
|
No one can say for sure what happened, but when he was
found, George clearly showed signs of struggling. A medical
|
|
|
examination revealed a severe inner-ear injury, and
whether the descent pressure or his forced equalization caused
|
|
|
the rupture, the injury almost certainly caused vertigo, a
debilitating condition causing severe disorientation. In a |
|
|
cave system, with no natural light reference, and walls
that look the same no matter which direction you turn, vertigo
|
|
|
can be truly life-threatening. It deprives the diver of
any sense of up and down, sometimes inducing nausea and
|
|
|
severe anxiety. George probably fought some or all of
these feelings as he tried to find the exit. |
|
|
|
|
|
It's unclear whether George told his teammates to continue
their dive or if he signaled for the whole team to
|
|
|
terminate it, as he should have. However, it is clear that
this was planned as a three-man buddy-team dive, and no
|
|
|
part of the plan indicated that the team would split up.
With his buddies providing additional reference, George could
|
|
|
have made it through this accident with little more than a
painful ear injury and a good story for the local dive bar.
|
|
|
On his own, George's story proved much more tragic. |

*Lessons For Life* |
|
|
|
|
|
*Dive your plan.* A dive plan provides a template to
follow in case something goes wrong--violating it invites disaster. |
|
|
|
|
|
*Stay with your buddy.* You dive together so you'll have
help in times of need. Be there for each other. |
|
|
|
|
|
*Never leave injured or disoriented divers* to fend for
themselves. Certain medical problems and massive disorientation
|
|
|
can leave even very experienced divers in need of
assistance. |
|
|
|
|
|
*Never force equalization.* Clear your ears often, well
before you feel any discomfort. If you feel pain, ascend until all
|
|
|
discomfort is gone and try equalizing again before
descending. |
