1.Composition of body fluid
Total body fluid
~50% in women, 60% in men

ICF : 55 ~ 75 %
ECF : 25 ~ 45 %
¼ -> intravascular(plasma water)
¾ -> extravascular(interstitial)

Osmolality : solute or particle concentration
milliosmoles per kilogram of water (mosmol/kg)

Major ECF particle : Na+, Cl– and HCO3–
Major ICF particle : K+ and organic phosphate esters

Urea : ineffective osmoles
-> Do not contribute to water shifts

Body fluid distribution in fluid theraphy

1. Water (5% DW) -> TBW (IVV로 1/12)
2. N/S -> ECV (IVV로 ¼)
