Fluids and Sodium ~ Diabetes Insipidus 까지..Fluids and SodiumPathophysiology- Total Body Water(TBW); 60% of body weight, divided into ICF and ECF.- ECF; composed of intravascular fluid, extravascular fluid,or interstitial fluid. - Three equilibrium; ostmotic, electric, acid-base. -> fluid의 behavior를 조절한다. - key point;- Na+ much more concentrated in ECF (약 140mEq/L) than ICF (약 10mEq/L), ECF에서는 intravascular와interstitial(extravascular) 사이 세포막이 water와 electrolyte에 permeable하기 때문에 농도가 같다.- 반면, 세포막에서는 water는 permeable하지만 electrolyte는 아니어서, intra..........
