Lemmens et al developed an indexed blood volume equation for obese and morbidly obese patients. The authors a re from Stanford University.
Patient selection: obese or morbidly obese
Parameters:
(1) body mass index (BMI) from height in meters and weight in kilograms
indexed blood volume in mL per kg =
= 70 / SQRT((BMI) / 22) =
= 70 * SQRT(22) / SQRT(BMI) =
= 328.329 / SQRT(BMI)
Figure 1 shows the line running from 10 to 70 kg per square meter.
