serum osmolality造句

• Normal serum osmolality is 280 & ndash; 296 mOsm / kg.
• A low serum osmolality will suppress the release of ADH, resulting in decreased water reabsorption and more concentrated plasma.
• A Cochrane review on this subject defined water-loss dehydration as " people with serum osmolality of 295 mOsm / kg or more " and found that the main symptoms in the elderly were expressing fatigue, missing drinks between meals and bioelectrical impedance analysis.
• However, looking at two totally different formulas for the expected serum osmolality [ https : / / www . khanacademy . org / test-prep / mcat / physical-sciences-practice / physical-sciences-practice-tut / e /-using-a-freezing-point-depression-osmometer-to-measure-serum-osmolality, what they have in common is that the concentrations of sodium, glucose, urea and in one potassium are used to come up with a figure that, in the second, is about 280-300 mOsm, ( this says 275 to 290-if I were anywhere near serious I'd need better sources than any of these, but this is strictly back of the envelope / order of magnitude ) where apparently 1 Osm = 1.86 K freezing point reduction ( that number being the cryoscopic constant ).
