"Nitrox poisoning"-tv dialogue

[DaleC]

Not without helium................

How about hypoxic nitrox?

great for cheapskate deep divers

My ears are burning!!!

It's a freaking TV show folks.
I never in my 25 year Navy career ran into a LT. Master Diver. I have ran into several Diving Officers. Master Diver is assigned as an enlisted NEC, I know a lot of Chief Petty Officer Master Divers. As it is kind of hard to earn I doubt officers could qualify.

And we're freaking having fun with it! :tongue:

I have the episode DVR, and they should have referred to Oxygen Toxicity and Trimix (Hypoxic). I also notice a single Nitrox tank at the crime scene, but Abby had doubles on her lab table.

Yup, OMS' finest. Couldn't tell if they were 98s or 112s, but the boots are unmistakeable.

Oxygen Toxicity can kill. Hypoxic Trimix is used for deep dives but will kill at shallow depths.

I am thinking the CGIS agent will be Gibbs 5th wife.

Nah, not going to happen. If he didn't go for the Lt. Col., and even if the lady legal shark doesn't keep him busy, Gibbs plus his female half on a regular basis would be too much of a good thing.

Well of course he died if he had boots on his tank! What a stroke!!

Well ... technically it will cause you to pass out, in which case you will most likely drown.

Folks, this ain't rocket surgery. Think of oxygen as the "power" that runs your body.

OK Bob, if you're gonna go all "Mr Wizard" on us, but incorrectly, I'm gonna call you on it.



You should not think of oxygen as the power to run your body, any more than oxygen is the power to run your car.

Glucose is the "power" that runs your body, it is metabolized in your body's cells to produce heat and adenosine triphosyphate, (ATP) a molecule that stores and releases energy as required by the cell. This metabolism requires oxygen, just like the combustion in your car's engine requires oxygen. The O2 itself isn't what is burned - the gasoline is - but the fire cannot burn without 02 to support the reaction.

Folks, this ain't rocket surgery. Think of oxygen as the "power" that runs your body. Like electricity to something that's powered by it ... too little won't "kill" the device ... but it won't run it either. Too much could cause some real damage ... but your body has a built-in inhibitor that simply stops you from taking in anymore.

Neither too much nor too little oxygen will directly kill you ... but it causes you to lose consciousness (too little) or go into a seizure (too much) where you lose control over your muscles. In either case, the real danger is drowning ... because you're most likely going to lose the reg outta your mouth and then when your automatic breathing responses kick back in you're gonna inhale water.

It really is that simple ... at least at the level most divers need to understand how it works.

Bob I fully agree but most divers are like most people walking on the streets. They know that they need oxygen to breathe but never sit down and learn the way our bodies use oxygen. Just like most people dont know how to change the oil in their own cars so they take to it to a specialist.

You are correct about oxygen being an engergy source as if you climb mountains where the air gets thinner alot of people become lightheaded and even faint. While the medical effects are there it is rare that people who take in to little oxygen die as a result. Usually when they pass out their needed intake decreases as their body goes into a state of rest.

Wasn't trying to go "Mr Wizard" at all ... which is why I included the caveat at the end of my post.

Simplifications work quite well for most things involving scuba physiology ... unless you're trying to teach it to a surgeon (ask me how I know that) ...

But saying that breathing a hypoxic mix will kill you is misleading ... it won't kill you. It'll make you pass out. Being underwater when you pass out will cause you to drown ... which is what will kill you ...

Once you start taking television shows serious, instead of a simple from of entertainment, you are setting yourself up for disappointment.

NCIS is a good show but CSI Miami, now that's great comedy!

Thanks Bob I could not have said it better (Nor was I thinking about the drowning part)
