Urine osmolality tuaj yeem kwv yees tau tseeb thiab meej siv cov zis urea, sodium thiab qabzib nrog cov lej hauv qab no: U osm=1.25 × urea (mmol / l.) lossis 20.87 × urea (g / l) + 1.1 × sodium (mmol / l) + 67 × qabzib (mmol / l) lossis 3.72 × qabzib (mg / dl).
tso zis osmolality ntsuas li cas?
Kev ntsuas osmolality tso zis ntsuas qhov concentration ntawm cov khoom hauv cov zisOsmolality kuj tuaj yeem ntsuas tau los ntawm kev kuaj ntshav. Cov txiv neej thiab poj niam urinary tracts kuj zoo ib yam, tshwj tsis yog rau qhov ntev ntawm cov urethra. Kev kuaj osmolality ntsuas qhov concentration ntawm cov khoom hauv cov tshuaj.
Koj suav osmolality li cas?
The equation: Posm=2 [Na(+)]+glucose (mg/dL)/18+BUN (mg/dL)//2.8 kuj yog cov qauv yooj yim thiab zoo tshaj plaws los xam cov ntshav osmolality. Qhov concentration ntawm osmoles zoo nkaus xwb ntsuas osmolality los yog tonicity zoo li: Eosm=2 [Na(+)] + glucose/18. Qhov ntau yam ntawm plasma tonicity yog 275-295mOsm / kg dej.
Koj ua li cas xam cov ntshav thiab cov zis osmolality?
Ib hom qauv yooj yim rau cov ntshav osmolality yog: Xaiv osmolality=2 x serum sodium + serum glucose + serum urea (tag nrho hauv mmol / L) Osmolality kuj tuaj yeem ntsuas los ntawm ib osmometer. Qhov sib txawv ntawm tus nqi ntsuas thiab ntsuas tus nqi yog hu ua osmolar gap.
Qhov tso zis osmolality yog dab tsi?
Ib tug neeg uas noj zaub mov zoo thiab haus dej ib txwm muaj cov zis osmolality ntawm kwv yees li 500-850 mOsm/kg dej.
