Diffusion of Carbon Monoxide and Hydrogen Cyanide to Muscles and Blood—An Experimental Study

Toxics, 2022
Postmortem carbon monoxide (CO) and hydrogen cyanide (HCN) diffusion under ambient conditions was assessed in a human cadaver model. The main objective of this study was to determine whether the postmortem diffusion of HCN and CO greatly affected the ...

Endogenous Carboxyhemoglobin Level Variation in COVID-19 and Bacterial Sepsis: A Novel Approach?

Microorganisms, 2022
Background: The increased production of carbon monoxide (CO) in sepsis has been proven, but the blood level variations of carboxyhemoglobin (COHb) as a potential evolutionary parameter of COVID-19 and sepsis/septic shock have yet to be determined.

Use of Carboxyhemoglobin as an Early Sign of Oxygenator Dysfunction in Patients Supported by Extracorporeal Membrane Oxygenation

Frontiers in Medicine, 2022
IntroductionPlasma free hemoglobin is the gold standard for monitoring hemolysis in extracorporeal membrane oxygenation (ECMO) but its routine use has some limitations. Carboxyhemoglobin (HbCO) is also a marker of intravascular hemolysis.

Effects of different fresh gas flows on carboxyhemoglobin levels: non-invasive carbon monoxide monitoring

, 2022
To observe the effect of different fresh gas flows (FGF) on carboxyhemoglobin (COHb) levels non-invasively and continuously and to determine the contribution of the smoking status to intraoperative carbon monoxide (CO) accumulation and respiratory ...

Incidence and risk factors for carbon monoxide poisoning in an emergency department in Nepal

Toxicology Communications, 2022
Incidence of carbon monoxide (CO) poisoning in Nepal has not been studied. The objective of this study was to evaluate baseline carboxyhemoglobin (COHb) concentrations, population risk factors, and incidence of CO poisoning at a single hospital in Nepal.

Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites

Safety Science and Technology, EarlyView.
Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.

Blood Carboxyhemoglobin Concentrations as a Diagnostic Biomarker of Hemolytic Anemias in Cats. [PDF]

J Vet Intern Med
Background Endogenous carboxyhemoglobin (COHb) production is a byproduct of hemoglobin metabolism. Hypothesis Blood carboxyhemoglobin concentrations are higher in cats with hemolytic anemia (HA).

A Novel Plasma Heme Assay Reveals Disease Severity in Beta‐Thalassemia and Sickle Cell Anemia

American Journal of Hematology, Volume 101, Issue 7, Page 1706-1716, July 2026.
ABSTRACT Anemia results from imbalanced hemoglobin or red blood cell production and clearance. Hemolytic anemia, caused by premature red blood cell removal, can be intravascular (in blood) or extravascular (erythrophagocytosis). Hemolysis is common in Sickle Cell Disease (SCD) and Beta‐Thalassemia anemia (β‐thalassemia), the most prevalent inherited ...

Mathematical model to evaluate the effect of carbon monoxide exposure as a function of gender, age and height

Journal of Applied Sciences and Environmental Management, 2019
This study develops and solves mathematical models using a time-dependent Fick’s law of diffusion with the tools of non-Newtonian mechanics specifically the power-law fluid model with appropriate boundary conditions to predict the concentration profiles
