Bu hasapçy hakda
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.
Köp soralýan soraglar
Mosteller BSA formulasy näme?
BSA (m²) = square root of (height in cm × weight in kg ÷ 3600). It is the most common formula because it is easy to calculate but closely matches more complex equations.
Näme üçin bedeniň ýüzi dermançylykda ulanylýar?
Birnäçe derman dozasy — aýratynam kemoterapiýa — we ýürek indeksi ýaly ölçegler, agramy däl-de BSA-a ölçelip bilner, sebäbi ýüz meýdany beden kütlesinden has ýakyn metabolizm derejesini gözleýär.
Normal bedeniň ýüzüň meýdany näme?
Ortaça ýetginjekler aýallar üçin 1.7 m² we erkekler üçin 1.9 m² töwereginde düşýärler. 175 sm, 75 kg adam Mosteller formulasy boýunça 1.91 m² töwereginde düşýär.
Bu esbap näme üçin birnäçe BSA formulalary görkezýär?
Mosteller, Du Bois, Haycock, Gehan-George we Boyd her biri dürli ölçemeli mysallardan alnan, şonuň üçin olaryň sanlary azça tapawutlanypdyr. Olar tipiki ýetginjekler üçin bir näçe göterim içinde ylalaşýarlar, we Mosteller hem ýönekeý hem dogry bolmagy üçin halanylýar.
BSA nädip dermanyň mukdaryny hasaplamak üçin ulanylýar?
Dozlar her kare metre miligramda BSA bilen köpeldilýär - şuňa görä 100 mg/m² derman 1.9 m² BSA bilen 190 mg berýär. Hakykatda dozaj bir kliniki tarapyndan bellenýär; bu esbap diňe ýüzüň meýdanyny hasaplaýar.
Beýikligi santimetr ýa inçde girmelimi?
Ya-da — laýyk gelen birlikleri saýla we esbap sentimetr we kilograma öwürer, formulalar buny talap eder. Mosteller özüçe bir santimetr boýy bilen kilogram agyrlygyň 3,600 bilen bölünen dörtburç köküdir.
