So I understand the fluid only shifts between the ECF and the ICF if there is a difference in osmolarity.
Does this mean that if I give a patient 3L of pure water, then the ICF will expand by 2L and ECF will expand by 1L?
Also, if I give someone 4L of isotonic saline, the ECF expands by 4L right? Therefore my plasma volume is now increased by 1L (1/4) and interstitial volume is increased by 3L (3/4).
So if I started bleeding out and lose 3L of blood, does this mean to replenish all that (plasma volume) I would have to give myself 4L of isotonic saline to raise my plasma volume by 3?
Just making sure I understand this correctly. Thanks!!!
