Surface Marker Buoy and Air Share

The heart works less in a horizontal position as compared with vertical thereby off-gassing with more efficiency. Where is TSandM when you need her?

Probably working far away from here...:depressed:

Sorry I haven't read the most recent posts except for this one...I need a break!:crazyeye:

Please let me know if I am being too technical.

Ypu would be referring to gravity issues and pooling blood....not part of the underwater issue we are now on....

I forgot to mention that we practice hovering, air share, deploying the SMB, and ascending, all horizontal.

Don't worry ScottL, you are the least of my headaches...

A few thoughts....

If you inflate your bag by turning your head and allowing your exhaust bubbles to go into the bag (hold the opening above the exhaust) you leave the regulator where it belongs, in your pie hole. Filling a bag my purging a regulator is very bad ju-ju where I dive, because of ice formation/free flows. Just food for thought. There are pros and cons to the different ways of inflating the bag, thats how I do it.

The minimal movement at deco has more to do with the high PPO2s involved than anything else. SLOW swimming probably won't hurt you any.

Someone mentioned the fact that a can of soda looses disolved CO2 faster if you shake it, which is true. If you want the nitrogen out of your blood fast, just forget the deco, get on the boat and do some jumping jacks. Just like the can of soda, the nitrogen will come out, fast, by FORMING BUBBLES!!!!!

Lets review, the whole idea behind staged deco is to get the inert disolved gases out of our blood while keeping the bubbles to a minimum.

Very true. My slow swimming is to attempt to keep my heart rate around 90 or 100 bpm( my max HR being 196) as opposed to my resting heart rate which is around 50, and could get lower in a water/relaxation environment( mamalian diving reflex, freedive training, etc). I like the idea of enhancing blood flow with very mild swimming while I am still at my deco stops underwater....However, once I reach the surface, I am then going to be doing no exertion at all...At least for the next hour or so.

FYI -- TSandM was sleeping after doing her third night shift in a row and in preparation for her 4th 8 p.m./8 a.m. shift (which is now finished). She's on her way home (150 mile drive) as I write.

Hi Peter,
My understanding is that blood flow in the lungs will be effected to a greater degree when the body is vertical ( in water). Pressure differential between the bottom of the lungs and the top of the lungs when vertical, will prevent optimal bloodflow at alveoli level , compared to best bloodflow when horizontal ( less pressure differential with smaller top to bottom distance when lungs are oriented this way) ...the lungs being a powerful "filter" for removing bubbles, and the increased efficiency of horizontal being one more safety tool at our disposal. This was a WKPP idea.
REgards,

If that is the case, I am wondering why in my OW class we were all vertical! well let's not open this can of...

Regarding on how to inflate our humongous SMB we will try all the different systems that have been mentioned here and maybe discover news ones and pick the one that works best when we also have to share air.

Bob I understand that a smaller SMB would be enough for the calm waters of Puget Sound but that's the SMB we have and we like challenges...

DaleC Sam and I are aspiring to become a Unified...etc...etc...Team (I cannot even remember the whole name!) but what if the needer hasn't ever heard of U...etc. and doesn't practice air share and other skills like technical divers or us do? It seems to me that in scubadiving there is nothing 'black and white'
