btl_nycSince hypertonic solution was added, osmolality has to go up. The degree of the hypertonicity doesn't really matter. The fluid flowing out of the ICF will increase ICF osmolality. Since water follows salt, the water's gonna flow only until the ECF and ICF have the same tonicity. So if the ICF osmolality went up, the ECF osmolality also had to go up, because they both need to be equal after the water is done equilibrating.+72019-06-30T23:09:12Z
krewfoo99ECF fluid is hypertonic because we infused an hypertonic solution.
ECF volume is going to go up because A) we added more volume via injection B) Sodium attracts water, and since hypertonic solution was given water goes from ICF to ECF
ICF volume decreases because the water is going to ECF. This causes an increase in Intracellular osmolarity, since you have more solutes compared to water (Less water to dilute it)+2019-10-20T19:44:41Z
