Surface area (SA) represents the surface of the skin that is exposedBody weight (BW) of an individual, typically expressed in kilograms (kg), is included so that the dose is normalized to that value.Temporal parameters in the dose equation include: Exposure frequency (EF) refers to the frequency with which the exposure occurs and might be provided in events per year or events per day.  |  F.A. Please advice if this is right? Body Surface Area Calculator. Materials and methods:The study group consisted of 294 medical students (146 women, 148 men) aged 18-25 years and bilateral hand tracings were obtained from all subjects. A representative subset of the entire sample population involving 12 men and 12 women (G24) was selected for detailed measurements of hand surface area (SAhand) and ratios of surface area to volume (SA/VOL) of various body segments. The development of three dimensional laser scanning technology and sophisticated graphics editing software have allowed an alternative and potentially more accurate determination of body surface area (BSA). The internal surface area of the gastro-intestinal tract has long been considered to be between 180 and 300 square meters. Authors P Tikuisis 1 , P Meunier, C E Jubenville.

The SA/VOL ratios of the various body segments were higher for the women compared to the men of G24, significantly for the head plus neck (by 7%), torso (19%), upper arms (15%), forearms (20%), hands (18%), and feet (11%). Raw whole-body scans of 641 adults (395 men and 246 women) were obtained from the anthropometric data base of the Civilian American and European Surface Anthropometry Resource project. The calculator below provides results for some of the most popular formulas. I was immediately interested, because I've been steeped in height and weight numbers for years now, trying to complete my photographic height weight chart. Epub 2015 Feb 24.

Average Lifetime Heart Beats Approximately 3,363,840,000 times if you live to be … Racial Differences in Cardiovascular Biomarkers in the General Population. Estimating Body Surface Area (BSA) To estimate your body surface area our BSA calculator uses the following formula [1]: 0.20247 x height (m) 0.725 x mass (kg) 0.425. where height is in meters and mass is in kg. 1 decade ago. We wrapped him in a tight skin of aluminum foil, then unwrapped it and measured the area of the flat foil. The human foot takes an incredible amount of abuse; I sometimes wonder at how such a complicated system of bones, joints, and tendons can do such a complicated task thousands of times per day, while a toaster only cooks bread, on a level surface, but lasts a fraction as long as the average foot! To determine the growth rate of the human heart in relation to body surface area, normal data obtained by echocardiography and angiocardiography were analyzed with respect to changes in body size occurring between infancy and adulthood.

The human brain is distinctively larger than that of any other primate, mainly due to the great expansion of the cerebral cortex (Rakic 1995). Separate non-linear regressions for each sex yielded the following best-fit equations (with root mean square errors of about 1.3%): BSA (cm2) = 128.1 x m0.44 x h0.60 for men and BSA = 147.4 x m0.47 x h0.55 for women, where m, body mass, is in kilograms and h, height, is in centimetres. surface area in the movement of heat, the use of a mathematical model of the relationship between an animal’s size and its metabolic rate, and a few questions about the importance of high surface area:volume ratios in the lungs of animals.

A student calculated the average surface area-to-volume ratio of four different types of human epithelial cells. Various prediction equations were tested and although most predicted the measured BSA reasonably closely, residual analysis revealed an overprediction with increasing body size in most cases. On average, the surface area A of human beings is related to weight W and height H . Int J Numer Methods Heat Fluid Flow. "The surface area may be calculated by multiplying 0.007184 times the weight in kilograms raised to the 0.425 power and the height in centimeters raised to the 0.725 power."

The foot was measured using a high-resolution 3-D foot scanner, of which the precision and accuracy is within 1%. Direct measurement of BSA is difficult, and as such many formulas have been published that estimate BSA. Various calculations have been published to arrive at the BSA without direct measurement.
