Carboxyhemoglobin Elevation in Trauma Victims

The Journal of Trauma: Injury, Infection, and Critical Care, 1999
Products of the hemeoxygenase enzyme include carboxyhemoglobin (COH) and bilirubin, which have protective effects in stressed states. Hemeoxygenase-1 enzyme up-regulates in states of oxidative stress. We hypothesized that COH is elevated in septic trauma patients compared with nonseptic patients.A prospective study was carried out at a Level I trauma ...

Carboxyhemoglobin Concentrations in Normal Cattle

American Journal of Veterinary Research, 1975
SUMMARY Percentage carboxyhemoglobin (HbCO) values were determined in 29 cows and 24 bulls in Minnesota during the summer of 1973. Results indicated that, in normal cattle, the HbCO value was 0.3%. Individual and daily variations in these values were recorded in 2 calves.

Estimation of Carboxyhemoglobin

Environmental Science & Technology, 1999
Carbon monoxide can be lethal at concentrations of less than 0.1%. The kinetics and mechanism of its toxicology have been described elegantly by Coburn et al. (J. Clin. Invest. 1965, 44, 1899−1910):  CO combines readily with blood hemoglobin to form carboxyhemoglobin (COHb).

False Elevation of Carboxyhemoglobin

Pediatric Emergency Care, 2011
Carbon monoxide toxicity in infants and children, like adults, produce nonspecific symptoms with normal vital signs necessitating the serum measurement of carboxyhemoglobin (COHb). In infants, the COHb may be falsely elevated.Our goal was to report a case of suspected carbon monoxide toxicity in an infant and the likely cause of the falsely elevated ...

Elevated blood carboxyhemoglobin levels as an early predictor of phototherapy requirement in moderate and late preterm infants

Journal of Maternal-Fetal & Neonatal Medicine, 2019
Objective: Preterm infants are prone to increased bilirubin burden and display adverse outcomes if left unmonitored; therefore, predicting an increased bilirubin production is of paramount importance. Methods: We aimed to evaluate carboxyhemoglobin (COHb)

Carboxyhemoglobin in umbilical cord blood and maternal smoking

Journal of Perinatal Medicine, 2019
Background Smoking during pregnancy still exists in daily life but the effect on the newborn in the early stage of life is still unclear. This study investigates the normal reference range of carboxyhemoglobin (HbCO) in umbilical cord blood gas (UBG ...

Carboxyhemoglobin Levels in Banked Blood

Chest, 1984
To determine the prevalence of carboxyhemoglobin levels in banked blood exceeding Air Quality Standards (level of carboxyhemoglobin greater than 1.5 percent), we analyzed banked blood for the level of carboxyhemoglobin from 101 randomly selected samples. Of 101 units of banked blood, 49 (49 percent) had carboxyhemoglobin levels greater than 1.5 percent,

Temporal Variation of Carboxyhemoglobin Concentrations

Archives of Environmental Health: An International Journal, 1969
Carboxyhemoglobin concentrations ([COHb]) were measured in 15 subjects by analysis of alveolar air samples collected at two-hour intervals during waking hours on seven consecutive days. Overall mean values were 3.80% COHb for five cigarette smokers and 1.64% COHb for ten nonsmokers. Analysis of the results indicates that long-term average [COHb] can be

Carboxyhemoglobin Levels-Reply

JAMA: The Journal of the American Medical Association, 1975
In Reply.— The criticism by Radford, while provocative, fails in its mission because it does not deal scientifically with several critical factors essential to the correct interpretation of the COHb survey data. Dr. Radford advances the hypothesis that the mean COHb saturation values reported from our survey of approximately 15,000 nonsmoking blood ...
