how much is the interstitial fluid of TBW&ECF?




  #2

ECF 1/3
ICF2/3
interstitial 2/3 of ECF**
plasma 1/3 of ECF
TBW is 1/3 ECF+ 2/3 ICF as I remember

ECF-plasma volume=interstitial fluid
some books say 2/3 and some books say 3/4 of ECF for interstitial fluid and you can ONLY measure it indirectly!
[I prefer 2/3 because of the i in ICF and the i in interstitial]
{Talk about playing with numbers}


  #3

yup ,you r right.
BRS SAYS 3/4 OF ECF.
AND KAPLAN SAYS 2/3 OF ECF.


  #4

agree with th eposts above and just to add;
60-40-20 rule:
TBW is 60% of body wt
ICF is 40% of body wt and
ECF is 20% of the body wt
