Carboxyhemoglobin as biomarker of prematurity complications

Clinica Chimica Acta, 2023
Carboxyhemoglobin (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 ...

Shunt effect of carboxyhemoglobin

Critical Care Medicine, 1979
Estimation 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

Carboxyhemoglobin in Nonsmokers

Archives of Environmental Health: An International Journal, 1975
A 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.

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).

Admission Carboxyhemoglobin

Annals of Plastic Surgery, 2020
Background Carbon monoxide is a gas produced by the combustion of hydrocarbon products that binds to heme molecules, 240 times more than oxygen, producing carboxyhemoglobin (COHb). As a result of its high affinity, there is shift of the oxyhemoglobin dissociation curve, compromising oxygen transport and delivery to tissues. Our
