Re: how deep with a mouthful-reopen
Old thread of some interest even though a lot has happened since 2005.
1) So how deep do you go with a mouthfull from the surface (not eq the mask, not bringing up more)?
- me, some 22 meters.
2) And how deep without eq the mask.
- I took the sphera to 32 yesterday, amazing that it can take that (and that I can take that
3) And where do you take your last mouthfill?
- me, before 30 (6.3VC, pack 1 litre)
4) If you warm up with FRC's - can you take your mouthfill earlier/later?
5) And what is your greatest depth on a full exhale in water? (as in Q1 or earlier)

Anyone knowing the size of the sinuses and trachea down to the epiglottis?

I used to be quite happy reaching 10-12 meters with one mouthfill. But after re-reading Eric's doc and some discussion later I could go to 20-24 pretty consistently and a "pb" of 27 with one mouthfill (sphera and not equalizing the mask). This of course changes the nature of the technique completely! With that kind of mouthfill you could in theory dive to 70m with a fill at 10m - which is mind boggling (of course theory is not practice)
However making such a huge mouthfill is really taxing so I don't usually do that in deep dives. I haven't really tried lately but to make that happen you need to be clearly above the RV so I'd guess around 30 is my mark for doing a "proper" mouthfill.
The kind I used to do I can actually do by taking 3-4 negative packs into my cheeks. Don't really know where that limit would be...So far I haven't had a (full lung) dive where I could not bring air up with negative packing.
I think you could scale it something like this. If you can reach on a single mouthfill at the surface:
-less than 10m - it's not really a mouthfill is it
-10m - you can sort of call it a mouthfill, but you need to do it pretty deep to be of any use
-15-20m that's pretty good if you can do that consistently
-20-25m Really good, equalization should never be a limiting factor
-Over 25m - you're up there with the best (Eric I guess has the record at 32 or something)
To make the mark reliable the trials should be FRC or less, otherwise it's just too easy to bring a little air up without even noticing...

Having no time an water arround to check your questions Cebastien, I want to try to give you an awnser good as I can.
1) So how deep do you go with a mouthfull from the surface (not eq the mask, not bringing up more)?
- Have not tried it yet.
2) And how deep without eq the mask.
- Have not tried it yet, but your numbers are inspireing and I will test it in Sharm at the WC. Now I do my last mask equalisation arround 30m.
3) And where do you take your last mouthfill?
- at 35-40m , Though it's not, by a longshot, a balloon cheek fill.
I find it very hard, if not impossible, to transfer the air from a ballonlike filled mouth to my ears. Though a half mouthfull works much better and I can even do hands-free with a little help from the pressure on my sphera mask. Tips are welcome offcause!
4) If you warm up with FRC's - can you take your mouthfill earlier/later?
I don't do any warm-up dives anymore, instead I warm up on land and have a buddy do a chest stretch on me. This and a warm body helps to be much more relaxed, hence it feels like I've got plenty of air at 40-50m. This enables me to my 'half-mouth-full' past 40m very comfortly, use it hands free and have plenty of air still left at 60m.
5) And what is your greatest depth on a full exhale in water? (as in Q1 or earlier)
About 7m, FI feet first, Though I must add this was breathed out deep and forcefully, having a normal mouthfull of air for equalising my ears.
I once did a few experiments with these kind of dives, and those are very extreme. Not to be done without a very capeble buddy, being warm, nearby shore and O2.
A medical student has taken my pulse (heart rate) at 5m by hand on my neck while I was sitting, because a HR monitor declaired me dead going below 30 BPM. The pulse He repeatedly registerd was a gentle, strong, and extremely slow pulse of arround 17 BPM. I had a 60-70 bmp pulse at the surface. Those dives lasted about 1'45"- 1'55" as I did it all going slowly down and slowly hand over hand up, havin a bottom time of arround 20s. Note that I did those dives without any contractions, which in combination with the huge underpressure can easily damage lungs and airways.
That's in part why I think this exercise is especially dangerous to those who cannot do an empty lung dive of 2' without contractions.
Test with caution and good circomstances.

How deep with a single mouthfill? Well, I posted the following picture of the jazzman Dizzy Gillespie in another thread (http://forums.deeperblue.net/freedi...e-reflex-not-always-helpful-2.html#post669749) in reference to laryngocoel (inflated larynx), but it actually belongs here too. I think that with a mouthfill like this you can get easily to 300m
Please note: the photo is not photoshoped, but it's certainly not necessary to emphasize to those who know Dizzy
