Ordinates Osmolalities (Os) | Abscissae Volumes (V, V) | Ordinates Times Abscissae Solute (mOsm) |
Os1 = baseline | Ve1 = baseline EC | Os1 x Ve1 = baseline EC |
Os2 = final | Vi1 = baseline IC | Os1 x Vi1= baseline IC |
Os3 = infusate | V1 = Ve1 + Vi1 = baseline body water | Os3 x V3 = infused |
Os4 = Hypothetical EC osmolality after equilibration of osmolality in the EC but before any interactions between EC and IC | V3 = infusate (added) \V = final EC gain | Os4 x (Ve1 + V3) = final EC |
V +Ve1 = final EC | Os2 x (Ve1 + V) = final EC, Note: Os4 x (Ve1 + V3) = Os2x(Ve1 + V) | |
V – V3 = osmotic volume transfer from IC to EC | [Os]2 x (Vi1 – [V – V3]) = final IC, Note: [Os]2 x (Vi1 – [V – V3]) = Os1xVi1 | |
Vi1 – (V – V3) = final IC |
