Ear pain from pressure, known as middle ear barotrauma,
is pretty common among divers; it's estimated
that more than half of experienced divers suffer it underwater.
One man found a novel way to rid himself of
symptoms -- and does so while diving. Should we follow
his lead?
At a recent Undersea and Hyperbaric Medical Society
session, Derek Covington, a professor of anesthesiology,
presented the case of a 46-year-old male diver who had
started to routinely carry a nasal decongestant spray
with him underwater after having difficulty with middle-
ear equalization.
He was 200 feet deep during one cave dive and
proceeding to the deepest point of a cave passage, at
290 feet, when he again had difficulty with middle-ear
equalization. He didn't want to abort the dive, so he
decided to self-administer the nasal spray underwater. This required him to remove his mask, block one nostril
and carefully sniff with the other. Despite the inevitable
inflow of water, he found he could replace his mask and
easily equalize the problematic middle ear. The diver
has subsequently followed the same procedure on other
dives and reported consistent success.
But Covington doesn't recommend you follow
this procedure. He stresses that this maneuver carries
many risks, including disorientation, loss of buoyancy,
coughing, sneezing, vocal cord spasms, and increased
susceptibility to oxygen toxicity of the central nervous
system. He recommends following the standard remedy:
Stop your descent at the first sign of ear discomfort to
allow time for equalizing, safely end the dive if you can't
equalize, abstain from further diving if your ears are still
feeling the pressure, and use a nasal decongestant or
spray (don't put any drops in your ears).
