Solute Excretion

programmed by Stephen Z Fadem

V = Volume in liters
CH2O=Freewater clearance
Cosm=Osmolar clearance =( Uosm X V)/Posm
V=Freewater clearance + osmolar clearance
Freewater clearance=V - osmolar clearance
CH2O=V(1- (Uosm/Posm))
Solute excretion=V X Uosm
V=Solute excretion/Uosm Free water=Solute excretion/Uosm X (1- (Uosm/Posm)

Urine Volume (liters)
Urine omolality (mosms)
Plasma omolality (mosms)
The U/P osm is
The Cosm is
The free water clearance is
The solute excretion is mOsm/day
Change solute excretion: mOsm/day (beer potomania might be 300 mOsm/day)
Free water clearance now is liters per day.
