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(More)
Intramolecularly crosslinked hemoglobins do not dissociate into alpha 1 beta 1 dimers. As a result, they escape glomerular filtration and have plasma half times of 4 hours. This value is shorter than for albumin (5.2 hours) with similar molecular weight but higher negative charge. The present study was done to determine if increased negative charge on a(More)
