Intravenous Fluids (IV) vs. human blood solute concentration

Post by fooballer » Sun Nov 12, 2006 1:41 am

i need help on a question with my lab report,

I was wondering why do IV fluids have to have the same solute concentration as our human blood?

thanks.

otherwise your red blood cells will shrink or even collapse and thus lose their function. The result is hypoxia and your tissues don't like that. It sets in motion some pathways leading to necrosis (cell death).

also all the hemoglobin in your plasma would affect your kidneys probably, not that you be alive to see that happening...

Check out osmosis and the terms hypotonic, hypertonic and isotonic and see how they relate to solute concentration in plasma and red blood cells and interstitial fluid.

It is not winning or loosing that is important...its all about how badly you beat the guy that comes in second that counts.
