Web8 okt. 2024 · A small rise in osmolality, even within physiological range (280–295 mOsm/kg), can trigger a brisk rise of circulating AVP. Hypovolemia, on the other hand, is a potent but much less sensitive stimulant. Greater than ~7% of volume depletion is needed to trigger AVP release. Once triggered, the rise can be sustained and amounts to a large magnitude.
