Malunga nale khadi
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 ebuzwa kaningi
Yini i-Mosteller BSA formula?
BSA (m²) = isikhala isitshalo (ubude cm × ubunzima kg ÷ 3600). Lokhu ifomu evamile kakhulu ngoba kulula ukulinganisa kodwa ngokusobala ifana ekulinganiseni ezinzima kakhulu.
Kungani indawo yobuso besikhumba isetshenziswa emkhakheni wezokwelapha?
Imithi eminingi esetshenziswayo—isibonelo, i-chemotherapy—ilinganiselwa ngokuya nge-cardiac index, futhi ilinganiselwa nge-BSA, hhayi ngobunzima, ngoba indawo yobuso ilandelela isilinganiso se-metabolism ngokucophelela kunanoma yisiphi isifiso somuntu.
Yini indawo yobuso besikhumba esijwayelekile?
Isilinganiso sobudala singaphansi kuka-1.7 m² kubantu besifazane no-1.9 m² kubantu abadala. U-175 cm, 75 kg umuntu ungaphansi kuka-1.91 m² ngefomula ye-Mosteller.
Kungani le thuluzi libonisa ifomu le-BSA elilodwa?
Mosteller, Du Bois, Haycock, Gehan-George noBoyd bonke bavela ezimbonini ezahlukene, ngakho-ke inani labo lihluka kancane. Bavumelana ngaphakathi kwephesenti elincane lobudala obujwayelekile, futhi Mosteller uthandeka ngokuba lula futhi ulungile.
Usebenzisa kanjani i-BSA ukulinganisa inani lemithi?
Izidakamizwa ezitholakala ngamamiligrami ngemitha emibili ziphindaphindwa nge-BSA yakho — ngakho-ke i-100 mg/m² yemithi e-BSA engu-1.9 m² inikeza i-190 mg. Ukwelashwa okusemthethweni kusethelwe ngumhlinzeki wezokwelapha; le thuluzi lilinganisela kuphela indawo yendawo.
Ngizofaka ubude ngesentimitha noma ngezintshi?
Noma — khetha amayunithi afanayo futhi ithuluzi liguqula zibe yisentimitha nekhilogremu, okuthi ifomu lidinga. I-Mosteller iyisitshalo esincane se-highness e-cm izikhathi zobunzima be-kg ehlukaniswe yi-3,600.
API — sebenzisa le calculator kusuka kukhodi
Nquma le calculator njenge JSON evulekile yendawo yokuqeda - akukho isithonjana esidingekayo. Thumela amaxabiso endawo ngezansi njengezilungiselelo zombuzo noma i-JSON.
