Hello all. A quick post to provide an update to what NEDU is up to, for those who are interested.
1. The OSF is definately back up to 100% operation, as we have conducted quite a number of dives since the Deep Dive in Jan. We have continued our "No-Stops" protocol to provide more statistical data on the 150 and 190 ft "No-D" times. We've also run a number of dives with some folks testing some new dry suit configurations in 35 degree water.
2. We're working on a contaminated water dive helmet now, seeing if we can get it to leak.
3. Getting ready to start up a protocol to actually quanitify the oxygen consumption of a diver working in various dive suits, from swim suit to dry suit.
4. Finished our inputs to revision 6 of the US Navy Dive manual. For the navy divers here, there are a number of changes in the new revision. You should be seeing it on the streets early this summer.
5. Met many folks in NJ at the Beneath the Sea convention. Thanks to all who stopped by the booth. I believe we are convention-less until DEMA next fall.
Well, the weather is getting warmer and its time to get back out in open water. To all of you who are dusting off the gear from the winter break, enjoy, be safe, and we'll see you around.
Cheers

Cool update, what helmet are you testing as a contaminated water hat?
Current test is on the KM-37.

Are you testing using a demand regulator or under positive pressure like a standard flow hat like the DESCO Pot?
Its basically a MK 21 surface supplied hat with some trick and tweaks on the exhaust side to keep water from coming back in through the out door.

This member has said "Thank you." to NEDU for this useful post:
What kind of "dry suit configurations" are you testing in cold water? Is it a different actual suit, or different undergarments? (She asks, who dives in cold water and has an intense interest in anything that works . . . )

Here is what they were using.
Core base layer: Under Armor Cold Gear
Core warm layer: 400-600 gram polar-fleece, personal preference
Socks: Smart wool wicking liner, Smart wool hiking sock, neoprene sock
Glove liner: OR Kodiak style glove liner
Head liner: Under Armor Head Beanie
Dry suit: DUI Model CF200X incorporated with zip-sealed gloves and a zip-seal neck/head combo
The divers had favorable things to say, I cannot ellaborate or risk sounding like I'm endorsing a product, which I can't do.

Do you guys presently have a way to measure bubbles in the blood? I know there's a Doppler method and a laser-Doppler, but those aren't sufficiently miniaturized yet.
It sure would be cool to be able to integrate that into a system of sensors. You'd be able to recognize DCS early and, possibly, limit the damage.
I know there's a Navy STTR out for that (I'm on the University of Iowa's team to develop a non invasive diver monitoring system). The issue of early DCS recognition really is stumping me, though. Any input or ideas would be helpful.

The O2 consumption information would be very interesting . . . It's cool that you guys can do this kind of research, and thanks for coming on here and telling us about it.

I only wish we did. No, we are like anyone else right now. Post-dive physical and wait for the diver to report that "something feels funny"
