Reset osmostat syndrome Reset osmostat, a subtype of SIADH, is a rare cause of hyponatraemia . It is due to secretion of ADH at a lower plasma osmolality. WebSIADH causes increased volume retention. It will induce hyponatremia (sodium concentration is determined by water volume in layman's terms) leading to Na levels of 120-130 mEq/L. Patients with Na <120 mEq will have severe symptoms with risk of cerebral edema or herniation. If you administer hypertonic saline, it will correct for serum sodium ... bingo under the hand dryer
