Dear stovers,
Under the thread:
(Stoves Digest, Vol 2, Issue 19) Re: CO monitoring seeking practical
analogues in local testing
methods for the 90% of the rest of us
I read A.K.'s good comment. All but one, he said about CO seemed me to be
right. So I looked especially for the numbers (look URL on bottom), because
I guessed to remember from learning a 200 times higher affinity of CO to
haemoglobin then O2. But it is still worse than I guessed,
and -I think- that is the reason that low CO-concentrations are so enormous
accumulating in haemoglobin by time.
In short my Google investigation out of the URL below:
-CO has about 250 times higher binding-affinity to haemoglobin than O2 ! !
-The halftime-binding of CO is normally 320 minutes.
-By hyper-bar-therapy, (breathing under 3 bar pressure) 100% oxygen, the
time (of half-time binding) is shortened from 320 minutes to 23 minutes.
-And additional, the physically solved O2 (-by breathing pure O2 at 3 bar
pressure-), fills the "lack of oxygen" during the time of competitive
inhibition for oxygenation in all tissues in that time of 23 minutes. In
that case the partial pressure of O2 is about 2200mm Hg, - while the
partial-pressure of oxygen is normally 80 to 100 mmHg when breathing normal
air at normal pressure (760mm Hg)
I relearned it by:

The charts included will tell you more than translation.
Thanks, to be stimulated to restudy some physiology! I did forget so much.
Possibly actualizing these facts, make all stovers, -as it does to me-, fear
CO a big portion more!
Kind Regards
Martin
P.S. If you are interested in details about CO and
health/medicine/prophylaxis, I just found another detailed toxicological
article (as well with some interesting tables) in German under:
