Hey everybody, welcome to scuba diver magazine, equalizing your ears is a fundamental skill for
scuba divers and freedivers but it s not a skill that we can show you like most other skills,
it s one of those skills that we have to try to explain to you for you to try yourself. And there
are a few ways of equalizing your ears, they re often called maneuvers. But, all we re trying
to do is to equalize a tiny air space inside a small tube between your throat and your ears.
To start with we re going to look at some general basic dos and don t to help improve
the effectiveness of these maneuvers because there are some points where even if you equalize
perfectly you simply won t be able to. So, to start with start equalizing your ears before
you even reach the water. I ll do it in the car journey and setting up my gear just to
get all of the parts moving and supple and ready to equalize when you re actually in the water
Salt water can cause tissues in your nose and throat to swell a little which can make
it harder to equalize so, in the water try to prevent any water from going up
your nose and in your mouth. I mean that s usually the plan anyway. But,
now you know that if you do get water up your nose it can make it a bit harder to equalize at times.
You also need to equalize early and often at the start of the dive because you can reach a depth
where the pressure around you can be so great that you can t equalize even if you re doing
it perfectly. That s why you ve probably heard the term early and often during your training
so that you never get to the point where you can t equalize. On the descent from the very start,
begin equalizing and keep going even if you don t feel anything, you should never feel any
discomfort in your ears and equalizing is all about technique, not force, if your ears aren
t equalizing, don t try harder because it could be that you ve gone so deep that the pressure
it too great. If you can t equalize, ascend and try again. Ascending relieves the ambient
pressure around you to increase your chances of equalizing properly and if it still doesn t work,
it s time to end the dive. If you keep descending you can really hurt yourself and it s better to
miss one dive than never be able to dive again. If you re struggling then being vertical in the
water can help mucus to drain as they naturally drain downwards and looking up and stretching
your neck can help. Valsalva
The most fundamental manouver you re taught is Valsalva where you pinch your nose and
blow. By blocking your nose and trying to exhale through your nose you inflate the
Eustachian tube by forcing that air in through the restriction which is why you feel that pop
and that s the air space that we re trying to equalize. Imagine a tube with a soft opening
that is naturally closed. As you descend that opening gets pulled in tighter as the air space
reduces in volume so we need to pump some air volume inside and equalize the pressure.
Valsalva is the most common technique that we teach because it s fairly easy to explain
and it works for most divers and it s a fairly recognizable hand signal also but,
it doesn t work for every diver and professionals often recommend other techniques so here
are some alternatives. Voluntary Tubal Opening
This one sounds a little gross, voluntary tubal opening, but it s the method that I tend to use
while diving, although I modify it a little. It s pretty simple and hands free and if you re doing
it right, with practice you can do it all the way down. Remember that we re trying to open that tube
in your throat. VTO is a lot like a yawn without opening your mouth. You kind of tense your jaw
and push your bottom jaw forward. That pulls and stretches at that opening which lets some air from
your throat into that air space and equalizes. To practice it, make yourself yawn and think
about which muscles are tensing and then recreate that. If you do it well enough on the surface,
you ll probably end up yawning. Toynbee Maneuver
Toynbee is the swallow maneuver. Pinch your nose but, instead of blowing, you re going to swallow.
Swallowing starts that peristalsis movement that, like VTO, moves and pulls things in your jaw to
open up that tube. Sometimes just the act of swallowing helps divers you don t always have
to hold your nose. Frenzel Maneuver
Frenzel is when you make a K sound, or move your mouth as if you re trying to make a K
sound and that tenses the back of your tongue which forces air in the eustachian tube. Again,
pinching your nose while you make that K movement can help trap the air so that when
you make that K movement the air has nowhere else to go but into the eustachian tube.
Sinuses
So, those are the basic maneuvers for equalizing your ears but, in some rare cases you can get a
squeeze in your sinuses which are tougher to equalize on the go. If you feel a sharp pain
in this sort of area when you re descending it s a sinus squeeze. It normally occurs if your sinuses
are congested, a trapped air space shrinks and can cause a capillary to burst and a small amount of
blood to enter your throat which can be quite bad for infections. The best thing is to either
avoid the dive completely if you re congested or abort the dive if you feel sinus pain.
There is also a flip side to this called the reverse block. A reverse block occurs at the end
of the dive when you re ascending. As you ascend the air spaces in your body expand, and with
your ears that excess volume just pushes itself out of the eustachian
tube and with normal clear sinuses it just migrates out. However, in some rare cases,
mucus can block an air space mid-dive and this trapped air is expanding with nowhere to go so
it stretches the sinus and can be very painful. The best thing to do is descend until the pain
stops and gradually ascend. Yet another reason to aim to end the dive with plenty of gas left
in your tank to give you as much time as possible to slowly ascend and give that gas a chance to
escape slowly. It usually can escape at a low rate but, if you try to rush it you can hurt
yourself. And again, don t be surprised if you get a nosebleed but, do get it checked out by a
physician before your next dive. Ideally an ENT doctor because things can get infected and it
s best to get it checked out. If you normally suffer with sinus problems, I m going to pop
a link to the DAN page on sinus barotrauma to look through, they go into much greater
detail about what s going on and what to do for you, the dive operator, and the physician.
If you re ever in doubt it is always better to go back and avoid the dive. You should
neve try to push past it, you re just going to hurt yourself and if you ever see your buddy
throw up the something wrong with my ears then go along with it and be wherever they need you
to be. If it s at the start of the dive then be prepared to head back to the surface and
end the dive there and if it s reverse block you need to think about what you can do to give your
buddy the most time as possible to ascend at a rate that doesn t damage their sinuses.
But, give these a quick try before your next dive and if one doesn t work for you then try another
or mix it up. Some divers combine techniques into something that works for them but, the
human body can be a crazy thing at times and if your normal technique doesn t work, try another,
if that doesn t work ascend and try again. It s always about equalizing early and often and it
s never about how hard you do the technique. You ll burst a blood vessel if you if you try to blow
too hard and it s more about the technique of how you equalize instead of how hard you equalize.
Hopefully that helped, as I said at the start, equalizing techniques aren t something that we
can show you but maybe my explanations helped and maybe gave you some other equalizing techniques
that might work for you. I myself use the yawning VTO, it means that I m hands free but,
I ll still pinch my nose if I need to. If you found this useful then please give the
