Carbon monoxide is a tasteless, odorless, colorless, and non-irritating gas formed with the combustion of hydrocarbons (fossil fuels). It binds to hemoglobin with a much greater affinity than oxygen to form carboxyhemoglobin, subsequently reducing oxygen-carrying capacity and oxygen utilization. Hyp...

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. Carboxyhemoglobin levels can...

Introduction  Carboxyhemoglobinemia is characterised by decreased oxygen delivery to tissues. In severe and critical coronavirus disease 2019 (COVID-19) illness with hypoxia, this can herald a grave and protracted course of illness. Patients with COVID-19 experience respiratory impairment, loweri...
