How would a nursing student work toward a RN career in hyperbarics? I'm not even specifically looking to work in a tropical location (I love the mountains), just at a facility somewhere because the field interests me. Obviously I dive. I'm good at math and love physics. I've been an EMT...

My Canon 40D's charger is kaput on day one and the battery is almost gone. Anyone know if there is a place to buy a battery charger for the Canon xxD xxxD Gx series on the island? Or some way to get it without paying $100 for fast international shipping?

I’m doing the 5/4 deal at Scuba Club Cozumel, but I have additional time at the end. Are there any dive sites out of Playa del Carmen that are key to see and worth tacking on to a trip that already includes 16 dives off Cozumel and 2 Cenote dives? What makes them different, unique? Any...

BACKGROUND: Taking a trip to Costa Rica to explore the jungles, volcanoes, whitewater kayak, and mountain bike for a week with my girlfriend. We also want to spend a second week diving. The problem is we were not planning on renting a car and would be staying on the east side of the country in...

Yes yes yes... plastic bag etc etc etc but <0.1% of my shutter cycles are underwater so I can'st justify the $$$ for a housing. The truth is I put my camera gear through much more danger in ski photography shooting in snowstorms and jumping off 40ft cliffs with no bag where I'm risking $6000 of...

I am interested in hearing from anyone who has experience with REMO2 field use or at least training. I would really like to know its real world effectivness, especially relating to its ability to function in ambient temperatures below 32F and altitude affects on function. Also, very...

Someone needs to tell a few paramedics and EMTs in the next county that just because they work on an ambulance and know how to use an ATV does not qualify them for swift water rescue... ESPECIALLY WHEN THEY DON'T KNOW HOW TO SWIM! They need to call the REAL swiftwater team when working in class...

Midnight... beeeeeeeeeeeeeeeeeeeep. Truck in pond, occupant out and talking. Get dressed, drive 10 minutes, stood down by dispatch. That's the norm lately. That's a good thing but it's getting old.

So here is a hypothetical that I've been wondering about for a while: Hypothetical 1: Diver takes a hit at 9000ft ASL. Nearest clinic 1: 10 minutes to a Level IV trauma "hospital" (read 24 beds total most of them ED) with no extended care at 9050ft often with a small unpressurized...

Where can I find a list of places that offer this certification course? How much does it usually cost? How long does a cert last and what are the CE requirements? How usefull is this course for EMTs who won't be doing anything with chambers (ie, field usefullness of training)? Opinions?

I really didn't know where else to ask this. I am hoping some of the technical types here would know the answer. When an O2 (or air) cylinder is given a volume rating ex: D cylinder is said to have 350L @ 2000psi or AL80 to have 80CF @ 3000psi, that means it contains enough gas to fill a...

"Breathing NitrOx reduces fatigue" I was told today. It seems like a silly concept except for maybe the shallowest of dives. Yes the %O2 is higher, but isn't it ppO2 that matters? If SaO2 is 100%, which I would expect any healthy person who is breathing compressed air at more than say 0.3...

Is an arterial gas embolism usually accompanied by pneumothorax? Can an arterial gas embolism be caused by something besides pulmonary barotrauma (or air in an injection)?

OK digital people... the film fanatic is at your mercy. We are looking for an inexpensive digital camera for use underwater (and in very wet environments above) to document dive rescue missions including: 1. Documenting wrecks 2. Object identification 3. Training review 4...

OK... so I'm going to buy my first digitoy... I decided on a 3MP toy camera for point and shooting. So does anyone have any opinions on the Canon A70 vs the Kodak DX6340?

Coffee... it's the stuff that gets you going in the morning when you are getting ready for work or are fighting a hangover. It keeps you going throughout the day. Coffee doesn't have to take like boiled mud. If you do it right it can be an amazing and complex mouth party. You can learn to...

First post after the board has revived! DING!

Wow! This is my 100th post and I can't think of anything cool to say.
