Halftime Tissue

[gehadoski]

Hi all

I don't know that if I spelled it right or not, I just want to make sure that I understand it correctly. I think that this means that the nitrogen time of the magor 5 cells will be 60 min on 60 feet. right?

I have no idea what you're talking about so I'll just give you some general information and see if that covers your question:

Most of the Haldane models are based on a number of "compartments" (12 or 16) and each compartment has it's own 1/2 time and it's own M value. The 1/2 time controls how fast a compartment fills or empties and the M value controls conservatism and supersaturation rates (ceilings and ascent profiles)

You can think the whole model as a deck of 16 differnt cards, each one unique.

Only one compartment (one card) will have the highest saturation state at a time. That's the controlling compartment and that's the one your computer shows you.

Imagine your computer as a sort of shuffler that always keeps the "most interesting" card on the top of the deck. The rest still get calculated but you only see one at a time. As your profile changes, your computer may shuffle a different card to teh top of the deck.

Does that clear up your question a bit?

that was exactly what I am asking about. Thanks alot that was very helpful. I think that at first when the American Navy start the scuba Diving and starts to calculate the halftime tissue, At that time there was only 5 compartments representing the major 5 tissues in the body which I think (bone, skin, cartliges, muscles, another one but I don't remember it).

Don't view them as tissues ... think of them as compartments for math purposes only. While a few have stated certain compartments represent certain tissues, they are not really thought of as representing a certain tissue or part of the body and are just for math purposes in calculating time limits or decompression stops.

Know I understand, thanks alot for the information. You were really helpful. Thanks alo for your time. I will do more research about that subject, if there is anything I don't understand I will ask you. Once again thanks for everything.
