RE: Digest 1C Re: THE RIGHT TO HEALTHY INDOOR AIR

[Guest guest]

Well said, Sharon! I believe Jim White has also reminded us in

the past that if we all agreed with each other all the time, none of us would

be learning (Jim said it a lot more eloquently, though). Here’s to the

continued pursuit of knowledge and understanding in the coming year(s).

Tony,

In response to the picture of a chilly winter day as seen out the

window of my office, you wrote, " That ain't winter. " It is

indeed winter. The facts show that I took that picture and posted it on

December 28, 2008. That is a date known worldwide to occur in the season

of winter.

What a great metaphor this makes. What I see and

what shapes my view when I share what the world looks like from

my office is not the same thing you see and shapes your view based on

what the world looks like from your office.

It proves the point: Life is simply a matter of perspective.

Scientifically speaking, the view from your office will never look the same as

the view from mine. That is an undisputable fact (supported by much evidence

over these past two years!)

Looking forward in 2009, to trying to decifer why you think

what you think based on your views and perspectives as I show why I

think what I think based on what is seen from mine.

Happy New Year To All,

Sharon

Uh, no, the main thrust of " Brazil " was that everything was

completely

and incompetently controlled by the government, and that any private

Response:

Good man. I call Brazil a cross between Orwell's 1984 and Monty

Python's the Meaning of Life (I have several version here).

2. You said:

a. " Based on what scientific studies are you concluding that

" Adding oxygen to the mix does nothing to limit or reduce the inhalation

of

the other crap. " ?

Doesn't adding oxygen change the mix of what people are breathing and

thereby reduce the relevant dose of the other " crap " ?

b. (Not sure " relevant dose " is the correct term, but I think you

know

what I mean) Why else would they use increased oxygen in hospitals? "

Response:

a. There is some data on respiration rate changes based on O2 levels (J

Physiol and some older Military data on humans and animals), but I think

's point is that unless you remove the other offending agents

(particles, vapors, gases) adding O2 is not going to do much. It's like

adding vitamin C to a fat-filled diet.

An example would Carbon monoxide that forms carboxyhemoglobin (COhb) at 400

times greater affinity than O2 binding. So increasing O2 relatively

slightly compared to CO does not move the transfer of O2 much.

Another might be heavy metals in ultrafines whereby the increase in O2 made

increase circulation and thus increase distribution of these particles.

b. O2 is used in hospitals because patients at higher concentrations

there is a diffusion gradient that increases O2 dissolution into the blood,

thus greater O2 available at the same cardiopulmonary rate.

This also relates to what barb said: " Given under increased barometric

pressure is also designed to deal with specific problems like wound healing,

infections " where they use Delta P (pressure) to drive the diffusion

instead

of increased Conc.

One of the general things that occurs with excess O2 is oxidation

(corrosion, free radical production, etc.) that is not necessarily good.

And finally, let's presume an asthmatic gets more O2 which is good during

inflammatory reactions because ones needs a certain amount to survive and

function; but radioactive deposition of particles in lungs was found to be

no different for non-asthmatics v asthmatics in actual radio-labeled

studies, so they are still depositing the same particles.

Winter days like today are among my very favorite

Response:

That ain't winter.
