Malunga nale Calculator
A body surface area (BSA) calculator estimates the total external area of your body in square metres from your height and weight. BSA is widely used in medicine to scale drug doses and physiological measurements. This tool uses the simple Mosteller formula and shows the classic Du Bois result for comparison.
Mosteller is a square root: BSA = √(height cm × weight kg ÷ 3600). For a 175 cm, 75 kg person that is √(175 × 75 ÷ 3600) = √3.65 ≈ 1.91 m². Du Bois, which raises height and weight to fractional powers, lands within a few hundredths of the same figure, which is why Mosteller is preferred for quick bedside use. The tool also reports the Haycock, Gehan-George and Boyd equations.
Body surface area matters most in dosing: chemotherapy and some other drugs are prescribed in milligrams per square metre, and measures like cardiac index are normalised to BSA because surface area tracks metabolic rate better than weight alone. Enter height and weight in metric or imperial and the tool converts internally. Dosing and clinical decisions belong to a clinician; this calculator is for reference only.
Imibuzo ebuza rhoqo
Yintoni ifomula yeMosteller BSA?
BSA (m²) = isikwere somthi we (ubude kwi cm × ubunzima kwi kg ÷ 3600). Le yifomula eqhelekileyo kuba kulula ukuyibala kodwa ifana ngokusondeleyo nee-equations ezinzima.
Kutheni isetyenziswa indawo yobuso besikhumba kwiyeza?
Iimithi ezininzi ezisetyenziswayo -kuquka unyango lwe-chemotherapy- kunye neendlela zokulinganisa ezinjengesalathiso senhliziyo zilinganiselwa nge-BSA kunokuba zilinganiselwe ngobunzima, kuba ubukhulu besikhumba bulandelela uxinzelelo lwemetabolism ngokusondeleyo kunesisindo somzimba.
Yintoni indawo eqhelekileyo yobuso bequlethe umzimba?
Abafazi abakhulu bawela ngama-1.7 m² kumabhinqa nakuma-1.9 m² kumabhinqa. Umntu oneminyaka engama-175 cm, obunzima obuyi-75 kg uwela ngama-1.91 m² ngefomula kaMosteller.
Kutheni le sixhobo sibonisa iifomula ezininzi ze BSA?
IMosteller, Du Bois, Haycock, Gehan-George kunye neBoyd zavela kuzo zonke izitokhwe eziliqela ezilinganisayo, ngoko ke inani labo lihlukana kancinci. Zi concorde ngaphakathi kweepesenti ezimbalwa zobude obuqhelekileyo, kwaye iMosteller ithandwa kuba ilula kwaye ichanekile.
I-BSA isetyenziswa njani ukulinganisa ukusetyenziswa kweyeza?
Iintlobo zemithi ezili-100 mg/m2 kwi-BSA yakho ye-1.9 m2 zinika i-190 mg. Ukusetyenziswa kwemithi ngokuqinisekileyo kucwangciswa ngumboneleli wezempilo; le sixhobo siqikelela kuphela indawo engaphezulu kwesikhumba.
Ndiza kungena ubude ngesentimitha okanye ngee-intshi?
Okanye - khetha iiyunithi ezihambelanayo kwaye isixhobo siguqula kwisentimitha kunye nekilogram, ekufuneka ifomula ifuna. I-Mosteller ngokwayo yi-square root yobude kwi-cm amaxesha obunzima kwi-kg yahlukaniswa ngama-3,600.
