Carboxyhemoglobin: a primer for clinicians

Undersea and Hyperbaric Medicine, 2018
One 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.

Impact of Methemoglobin on Carboxyhemoglobin Saturation Measurement in Fatal Sodium Nitrate and Sodium Nitrite Cases.

Journal of Analytical Toxicology, 2023
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 ...

Carboxyhemoglobin levels in children during extracorporeal membrane oxygenation support: a retrospective study

Perfusion, 2021
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, 2020
Aims: 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 ...

Determination of carboxyhemoglobin half-life in patients with carbon monoxide toxicity treated with high flow nasal cannula oxygen therapy

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.

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.
