I Need Homework Help!!!! Please?????
 
I know we have a few nurses on here so I thought I would ask...

What does the "Hg" stand for in the Partial pressure...

PCO2=0.3mm Hg

can someone just write it out for me???

daisy mae06 05-04-2008 05:39 PM
LOL Maureen you want me to Google it?

Proud Mommy 05-04-2008 05:40 PM
ive been trying for over an hour and nothing spells it out:mad:

I figured this was the closest i could get to a nurse:D

Proud Mommy 05-04-2008 05:42 PM
I am so frustrated because i cant get beyond this point... I dont like not understanding something:(

kalina82 05-04-2008 05:43 PM
mm of mercury?

kalina82 05-04-2008 05:44 PM
what's the problem you are trying to figure out?

daisy mae06 05-04-2008 05:45 PM
I was thinking Mercury too

Hg, the chemical symbol for mercury (element) (hydrargyrum).

I'll Do anything I can to help you ... you know I will :)

daisy mae06 05-04-2008 05:47 PM
or it could be

mmHg, or Torr, a unit of pressure

Proud Mommy 05-04-2008 05:47 PM
I found that it did stand for mercury but that seems strange to me because it is a blood gas:confused:

It is the pressure of gas in the lungs

It is being mesured in pressure but of gas but I dont know

daisy mae06 05-04-2008 05:49 PM
Hg - Wikipedia, the free encyclopedia

I knew it was mercury but as far as I know we dont have mercury in our lungs, thats why I am confused:confused::confused:

Proud Mommy 05-04-2008 05:57 PM
Im ready to chuck this book!!!

daisy mae06 05-04-2008 05:58 PM
I also found this

mm Hg - this stands for millimeters of Mercury. Standard pressure is 761.84 mm Hg.

not sure if that helps.

Thank you but I dont feal very smart right now:(:(

Proud Mommy 05-04-2008 06:17 PM
Ok I got a hold of my sister and she asked her friend who is an EMT and he said it is millimeters of mercury

Proud Mommy 05-04-2008 06:19 PM
That doesnt make sense right now but I have to move on:confused: Back to the book:D

Thank you for all your help!!! You always help me so much:D:D

Millimeters of mercury is the way we measure pressure - anywhere in the body where pressure can be measured. This is the way blood pressure is measured, in mm of Hg. Have you ever seen the old timey blood pressure machines that hang on the wall and have the silver liquid (mercury) that rises up when you pump up the cuff and then lowers as you let out the cuff pressure? We don't say 120/80 mm Hg, but that is what it is.

Anyway, the number that you cited in your first post is the partial pressure or tension of CO2 (the amount of carbon dioxide gas dissolved in the blood). No, there is no mercury in the lungs. I'm not sure in what context you are reading about PCO2, but anyway, that is what it means.

:thumbup::thumbup:

i had to go last night before you answered what it was in reference too. But this post explains it all. :)

mizzwanned 05-05-2008 06:41 AM
gosh we were just studying this in chem and i cant even answer it lol doesn't it have something to do with torr?

RowdysMom 05-05-2008 04:52 PM
YES! Torr is is another word for mmHg and both terms are used to represent a unit of pressure measurement. Torr or mmHg is the atmospheric pressure that supports a column of mercury 1 millimeter high.
