Whether it is because of physiological changes in the peripheral vascular system during pregnancy (increased plasma volume, decreased plasma osmolality and decreased peripheral resistance) that actually offset a severe vasospasm is not fully understood?

On the other hand, in large-type goats were fed dry forage for 2 h twice daily, after 40 min of the feeding period had elapsed, ruminal absorption of salts from the consumed feed causes an increase in plasma osmolality and both dry forage intake and salivary secretion significantly decrease while water intake increases (Sunagawa et al.
The measured plasma osmolality will exceed the calculated plasma osmolality.
Few studies have been done to determine reference ranges for plasma osmolality in birds.
An acute increase in plasma osmolality and acidosis may facilitate this movement of potassium (Hirota et al.
Use of the TTKG requires that the urine osmolality be greater than the plasma osmolality.
In SIADH, the body retains excess water, thus reducing the plasma osmolality by diluting sodium and causing hyponatraemia.
Several studies have demonstrated that reduced plasma osmolality is associated with increased cerebral oedema where the blood-brain barrier has been disrupted, (3) but these have not been translated into clinical outcome studies.
