Loosing mouthfill after passing RV at 48m

[WetBoy]

Hi !!

I am having a huge huge problem when it comes to deep diving. I can not get so much deeper than 55m.

My problem is that is always loose my mouthfill at around 45-48m which is just passed my RV with 15 lungpack. I get one swallowing reflex and the air goes strait to my stomac. I can not control the reflex....

There is no lack of training and experience in my case
----------------------------------------------------

Am doing a lot of RFC:s and emty lounges with good result without loosing my mouthfill and are actually able to get empty cheeks without swallowing it.
The problem occur in a real dive when reaching 50m:s dept.

Is my epiglottis invoulontary opening up ?
What could be the cause of this ? contraction starting ?

Is there some way to prevent the air to go to my stomac. Location of tongue ?
If the epiglotis is opening up how do i prevent this from hapening ?


I Have had this problem now for three years and it is driving me crazy. Pleeese help :crutch:crutch:crutch:crutch


Best regards WetBoy

After filling your mouth (20-30m), inhale against the closed epiglottis (creating a vacuum in the lungs). This creates a reverse suction against the epiglottis which forces it to stay closed. Be careful with this technique. If you are prone to lung squeeze it can increase the risk of squeeze.

Hi Eric !! thanx for your quick response.

Is the inhale against the epiglottis to be done only once immediately after the moutfill or should it be done a number of occacions during descend ???

Best regards

The same thing happens to me and after years of diving to 70 meters it is very frustrating. I have had limited success with a some hyperventilation to try to delay the pressure contraction but you know how dangerous that can be.
I thought that I had tried your suggestion Eric but I will work on it some more. Hope others will pick up on your thread Wetboy.

I recommend immediately inhaling against the epiglottis after the mouthfill and continue the lung vacuum as long as possible.

Hi,

One trick that has worked for me and a lot of others is "continuous equalization", ie don't do intermitted "equalizations", but after the mouthfill, do one really long one, keeping a slight positive pressure on your ears for the entire freefall.

At least for me that helps to keep the concentration and "feel" the air/pressure and it's much easier not to loose the mouthfill.

Not to mention that it's a really relaxing way to equalize, you just kind of stop worrying about it, just let your mouth shrink with the depth...

Ok, now that explains many things. Gotta give that a try!
