But Derek it's fun to watch the 'telephone line' passing of inaccurate information and urban legends!!!!! The really difficult part for me is when I was forced to wear different makeup so that I could 'match' the rest of the team. I still haven't gotten that razor stubble look down. :05:

:lol2:

We gotta get you some corks to burn for that 6 o'clock shadow look.

Ah, the DIY-DIR look.....I must have missed that section.

I was sooo busy studying George and Jarrod's bios that I must have missed it completely. But it's nice now that I wear the same tennis shoes and belts they do!!!

OUCH!!! Stop hitting me! Maybe an ice cream would make you stop?!? :icecream1

Ohhhhhhh, :icecream1.........that works.....:icon10:

i'm so sorry everyone, i understand the whole dead horse thing, but it's been several hours since i read this thread and i can't stand it.

hemoglobin has nothing whatever to do with blood pressure. nothing. it carries oxygen around, like santa or the easter bunny, distributing to all the good cells. contributing factors to blood pressure are many and varied, including baroreceptors (the reason you don't rub both carotids at the same time), and chemoreceptors which are part of the endocrine system feedbacks, both of which are tied in to things like cardiac output and the circular struggles of balancing preload and afterload. if the system doesn't have oxygen, it won't work, but only because the organism would be dead. except for that little glitch, the system doesn't care if it's circulating blood with plenty of hemoglobin, plasma, or pepsi.

i can't make any contributions to the gas law discussion, but this bit has bothered me and nobody challenged it at the time, so... but i apologize again for stirring the settled pot.

maybe a quick google of hemoglobin would inlighten you as to why nobody challenged this at the time. :14:

As far as Blood pressure goes this is one thing I found. (from this website http://www.mamashealth.com/Bloodpressure.asp)

Hemoglobin, the iron-protein compound that gives blood its red color, also plays a role in regulating blood pressure. However, hemoblobin's affect is usually localized and is not very useful when trying to control blood pressure on a large scale. Hemoglobin contains nitric oxide, a gas that relaxes the blood vessel walls, thus increasing blood flow. It controls the expansion and contraction of blood vessels, and thus blood pressure, by regulating the amount of nitric oxide to which the vessels are exposed.

As far as Partial Pressure and hemoglobin go....there is lots of info.

very good Jeff, relating this to a divers physiology isn't such a big step now.


zip, bang,blam SSSSSSSt..... The whole WOOOORLD is at your feet :11:

 

[BabyDuck]

from what i see, that only matters in HaH of alpha thalessemia. so not very widely applicable to all divers.

ah, I see , the saturation levels of partial pressures and human physiology do aply to all divers. that's why we use mixed gasses to dive . All breathing gas is made of more than one gas, and all those gasses have differant effects on human physiology

 

[BabyDuck]

no, i meant the hypertensive effect of nitric oxide with HaH. of course all breathing gas and partial pressures matter.

but i'll back up a bit and just say for healthy people, hemoglobin has a negligable effect on blood pressure compared to other controlling mechanisms.

Thats the point I was trying to get across with the snippet I put in my post.
