Age range for subjects: 3.5 to 41 years of age
blood volume in mL in males =
= (63.15 * (body weight in kilograms)) + 275
= (3187 * (body surface area in square meters)) - 1136
= 10^((0.008578 * (height in cm)) + 2.19)
= 10^((0.9406 * LOG10(weight in kilograms)) + 1.9577) <see NOTE>
= 10^((1.408 * LOG10(body surface area in square meters)) + 3.3034)
= (body weight in kilograms) * (75.7 - (0.114 * (body weight in kilograms)))
= (body surface area in square meters) * ((697.2 * (body surface area)) + 1312)
= (height in meters) * ((24.19 * (height in cm)) - 1524)
where:
• The equation using LOG10(weight in kilograms)) in Table I is given with 1.4577 rather than 1.9577. When the former is used, very low values are returned. I assumed that there was a typographical error since a 4 looks like a 9. Using a 9 gives much better values.
blood volume in mL in females =
= (52.13 * (body weight in kilograms)) + 520
= (2379 * (body surface area in square meters)) - 405
= 10^((0.007173 * (height in cm)) + 2.3457)
= 10^((0.8257 * LOG10(weight in kilograms)) + 2.0982)
= 10^((1.2082 * LOG10(body surface area in square meters)) + 3.2869)
= (body weight in kilograms) * (82.4 - (0.374 * (body weight in kilograms)))
= (body surface area in square meters) * ((360.5 * (body surface area)) + 1575)
= (height in meters) * ((14.39 * (height in cm)) - 352)
Limitations:
• The study was performed on 20 males and 21 females from 3.5 to 41 years, consisting of 2 Blacks, 2 Hispanics and 37 Whites. These numbers seem small. The technique of dye dilution would not lend itself to large numbers of subjects.
Performance:
• The correlation coefficients for the first 5 equations in males ranged from 0.96 to 0.99.
• The correlation coefficients for the first 5 equations in females ranged from 0.93 to 0.96.
• The correlation coefficients for the 6th, 7th and 8th equations are not very good.
