Carboxyhemoglobin levels in hemolytic disease of the newborn

The Journal of Pediatrics, 1962
The concentration of carbon monoxide, a normal metabolic product of hemoglobin breakdown, was measured in the blood of normal term infants and compared with that of a group of 23 infants requiring exchange transfusions for a variety of reasons. Normal term infants had a mean carboxyhemoglobin concentration of 0.42 per cent.

Compensatory tracking in humans with elevated carboxyhemoglobin

Neurotoxicology and Teratology, 1990
A total of seventy-four men divided into five groups performed a compensatory tracking task for 4 hr with group mean carboxyhemoglobin (COHb) levels of 0.9, 5.6, 6.1, 11.4 or 16.6%. In all but one group, COHb was formed in approximately 5 min by having the subject breathe a high concentration of carbon monoxide (CO) from a Douglas bag.

Dose-effects functions for carboxyhemoglobin and behavior

Neurotoxicology and Teratology, 1990
Literature on dose-effects functions of carboxyhemoglobin (COHb) and human behavior is internally inconsistent. A recent study was performed to describe such a function for tracking behavior in humans (7). No significant effects were found, however, even for COHb levels up to ca. 17%.

Carboxyhemoglobin Concentration in Fetal Cord Blood

Pediatrics, 1983
To the Editor.— Bureau et al1 reported that the concentration of carboxyhemoglobin (HbCO) is increased more than twofold in cord blood of newborns of smoking mothers as compared to corresponding values in maternal venous blood. Data were obtained from an IL 282 (Instrumentation Laboratory, Lexington) Co-oximeter, an instrument using ...

Study of photodissociation parameters of carboxyhemoglobin

Quantum Electronics, 2008
The general properties of photodissociation of carboxyhemoglobin (HbCO) in buffer solutions of whole human blood are studied by the flash photolysis method on a setup with intersecting beams. It is shown that the efficiency of photoinduced dissociation of the HbCO complex virtually linearly depends on the photolytic irradiation intensity for the ...

Rapid determination of carboxyhemoglobin in blood by Oximeter

Forensic Science International, 2003
Different methods to determine carboxyhemoglobin (COHb) in blood are described in the literature. In our laboratory three methods to analyze COHb in post-mortem blood samples were compared: the spectrophotometric method of Maehly, a gas chromatographic method with a thermal conductivity detector (GC-TCD) and the Oximeter.

Carboxyhemoglobin and brain blood flow in humans

Neurotoxicology and Teratology, 1992
It has been shown that with increased carboxyhemoglobin (COHb) and associated decrease in blood oxygen-carrying capacity, a compensatory increase in brain-blood flow (BBF) develops. The BBF response in humans has been shown to be quite variable. Two experiments were conducted in which humans were exposed to sufficient carbon monoxide (CO) to produce ...

Effects of carboxyhemoglobin on the determination of methemoglobin in blood

Biochemical Medicine, 1974
Abstract The Evelyn and Malloy procedure for methemoglobin determination in blood has been modified to decrease changes which occur in shed blood and in blood hemolysates. Immediate hemolysis, acidification to pH 6.9, and cooling to 0°C serve to minimize effectively metabolic changes in the MetHb content of shed blood and autoxidation in the ...
