Carboxyhemoglobin: a primer for clinicians
Undersea and Hyperbaric Medicine, 2018One of carbon monoxide’s several mechanisms of toxicity is binding with circulating hemoglobin to form carboxyhemoglobin, resulting in a functional anemia. While patients with carbon monoxide poisoning are often said to be “cherry-red,” such discoloration is rarely seen.

An increase in suicide cases by sodium nitrate and sodium nitrite ingestion has been noted in the scientific literature. We report on the possible impact of nitrate/nitrite-caused methemoglobinemia on carboxyhemoglobin measurement by spectrophotometric ...

Introduction: Hemolysis is a common complication of extracorporeal membrane oxygenation (ECMO). There are few data on whether carboxyhemoglobin (COHb), a potential marker of hemolysis, are elevated during ECMO support.

A Neglected and Promising Predictor of Severe Hyperbilirubinemia Due to Hemolysis: Carboxyhemoglobin
Fetal and Pediatric Pathology, 2020Aims: We investigated the relationship between total serum bilirubin (TSB) and carboxyhemoglobin (COHb) in term neonates with detected and treated hemolysis within a particular time frame with the aim of augmenting the case for early diagnosis and ...

Shunt effect of carboxyhemoglobin
Critical Care Medicine, 1979Estimation of intrapulmonary blood shunt fraction requires accurate evaluation of pulmonary capillary, arterial, and mixed venous oxygen contents. The presence of carboxyhemoglobin, as well as methemoglobin and sulfhemoglobin, may lead to large errors in the calculated intrapulmonary blood shunt fraction. The errors are most pronounced at low values of

Estimation of Carboxyhemoglobin
Environmental Science & Technology, 1999Carbon 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).

Carboxyhemoglobin as biomarker of prematurity complications
Clinica Chimica Acta, 2023Carboxyhemoglobin (COHb) is considered a biomarker of oxidative stress and previous studies suggest a correlation between its blood level and prematurity complications. Our aim in this study was to assess the correlation between COHb levels and the risk for bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), and retinopathy of ...

Clinical toxicology, 2019
Background: Acute carbon monoxide poisoning is a common environmental emergency worldwide. Treatment options are limited to normobaric oxygen therapy with a nonrebreather face mask or endotracheal tube and hyperbaric oxygen.

Carboxyhemoglobin Elevation in Trauma Victims
The Journal of Trauma: Injury, Infection, and Critical Care, 1999Products 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 in Nonsmokers
Archives of Environmental Health: An International Journal, 1975A study was made of existing mathematical models for both carbon monoxide (CO) and carboxyhemoglobin (COHb) buildup. From these models a combined model was derived for calculating delta%COHb in nonsmokers in an enclosed space in which excess concentrations of CO may occur.
