The absorption characteristics of fetal and adult human hemoglobin samples were determined for the range of 600 to 1,050 nm. Over this range, fetal hemoglobin absorption is nearly identical to that of adult hemoglobin. Since currently available two-wavelength pulse oximeters base their calculations of arterial oxyhemoglobin saturation on absorption at the wavelengths of 660 and 920 nm, we conclude that the accuracy of two-wavelength pulse oximetry previously demonstrated in adults can be extrapolated to infants with high concentrations of fetal hemoglobin.
测定了胎儿和成人血红蛋白样本在600至1050纳米范围内的吸收特性。在此范围内，胎儿血红蛋白的吸收与成人血红蛋白几乎相同。由于目前可用的双波长脉搏血氧仪是根据660和920纳米波长处的吸收来计算动脉血氧血红蛋白饱和度的，我们得出结论，先前在成人中证明的双波长脉搏血氧测定法的准确性可以外推至胎儿血红蛋白浓度高的婴儿。
