  2. Plasma osmolality - Wikipedia

    en.wikipedia.org/wiki/Plasma_Osmolality

    A low serum osmolality will suppress the release of ADH, resulting in decreased water reabsorption and more concentrated plasma. Syndrome of inappropriate ADH secretion occurs when excessive release of antidiuretic hormone results in inappropriately elevated urine osmolality (>100 mOsmol/L) relative to the blood plasma, leading to hyponatraemia.

  3. Osmol gap - Wikipedia

    en.wikipedia.org/wiki/Osmol_gap

    The osmol gap is typically calculated with the following formula (all values in mmol/L): = = ([+] + [] + []) In non-SI laboratory units: Calculated osmolality = 2 x [Na mmol/L] + [glucose mg/dL] / 18 + [BUN mg/dL] / 2.8 + [ethanol/3.7] [3] (note: the values 18 and 2.8 convert mg/dL into mmol/L; the molecular weight of ethanol is 46, but empiric data shows that it does not act as an ideal ...

  4. Osmotic concentration - Wikipedia

    en.wikipedia.org/wiki/Osmotic_concentration

    In simpler terms, osmolality is an expression of solute osmotic concentration per mass of solvent, whereas osmolarity is per volume of solution (thus the conversion by multiplying with the mass density of solvent in solution (kg solvent/litre solution).

    Normal serum osmolality ranges from 280 to 290 mOsm/kg and serum osmolality to cause water removal from brain without much side effects ranges from 300 to 320 mOsm/kg. Usually, 90 mL of space is created in the intracranial vault by 1.6% reduction in brain water content. [ 1 ]

    [1] [2] The delta ratio is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether mixed acid base disorder (metabolic acidosis) is present. The list of agents that cause high anion gap metabolic acidosis is similar to but broader than the list of agents that cause a serum osmolal gap .

    This Jennifer Aniston-fave serum stick is the ideal delivery system for softening fine lines, prepping skin for makeup and targeting dry patches (I've tried it — it actually blurred my wrinkles).

  9. Stool osmotic gap - Wikipedia

    en.wikipedia.org/wiki/Stool_osmotic_gap

    However, the solutes contributing to this total differ. Serum is mostly sodium and potassium salts (as reflected in the formulas for serum osmol gap and anion gap), while the digestive tract contains significant amounts of other compounds. Stool osmotic gap is a measure of the concentration of those other compounds. [citation needed]
