কীভাবে Osmolality গণনা করবেন
Osmolality কি?
Osmolality measures solute concentration in body fluids. It's critical for diagnosing hyponatremia, hypernatremia, and fluid disorders.
সূত্র
Calculate: Osm = 2[Na] + (Glu/18) + (BUN/2.8)
- Na
- Na value — Variable used in the calculation
- BUN
- BUN value — Variable used in the calculation
ধাপে ধাপে নির্দেশিকা
- 1Calculate: Osm = 2[Na] + (Glu/18) + (BUN/2.8)
- 2Normal: 280-310 mOsm/kg
- 3Compare measured to calculated osmolality
সমাধান করা উদাহরণ
ইনপুট
Na 128, glucose 200, BUN 28
ফলাফল
Osm ≈ 318 (high), measured lower suggests hyponatremia
Pseudohyponatremia likely
এড়ানোর সাধারণ ভুল
- ✕Neglecting glucose and BUN contributions in hyperglycemia/uremia
- ✕Confusing osmolality with osmolarity (different in concentrated solutions)
সচরাচর জিজ্ঞাসা
What's the osmolal gap?
Difference between measured and calculated osmolality. Large gap suggests unmeasured osmoles (ethanol, methanol, etc.).
How does osmolality relate to sodium?
Sodium is the main determinant of osmolality; hyponatremia usually means hypoosmolality and vice versa.
