Relationship between carbon monoxide poisoning, lactate and cardiac marker

Van Tıp Dergisi, 2019
INTRODUCTION: Carbon monoxide reduces blood oxygen transport capacity and causes tissue hypoxia by binding to hemoglobin. We aimed to evaluate the relationship between Troponin I, a myocardial injury marker, Lactate, a tissue hypoxia marker and ...

A Pilot Study of Inhaled CO Therapy in Neonatal Hypoxia-Ischemia: Carboxyhemoglobin Concentrations and Brain Volumes

Frontiers in Pediatrics, 2018
Objective: The objective of this pilot study was to start evaluating the efficacy and the safety (i.e., carboxyhemoglobin concentration of carbon monoxide (CO)) as a putative neuroprotective therapy in neonates.Study Design: Neonatal C57BL/6 mice were ...

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 ...

Significance of the carboxyhemoglobin level for out-of-hospital cardiopulmonary arrest

Journal of Emergencies, Trauma and Shock, 2012
Background: At low concentrations, carbon monoxide (CO) can confer cyto and tissue-protective effects, such as endogenous Heme oxygenase 1 expression, which has antioxidative, anti-inflammatory, antiproliferative, and antiapoptotic effects.

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.

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.

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
