Oct 15, 2010 · Carbon monoxide is a toxic gas. It combines with hemoglobin in the red blood cells, and makes it incapable of doing its normal function of transporting oxygen.

Delivery of oxygen can be calculated with the equation: DO 2 = CO x CaO 2. Where CaO 2 = [1.34 x Hgb x SaO 2] + [PaO 2 x 0.003] . The portion contributed by dissolved O 2 [PaO2 x 0.003] is usually negligible except in cases of extreme anemia (i.e. Hgb 5) or carbon monoxide poisoning.. Factors that affect the oxyhemoglobin dissociation curve will also affect oxygen delivery:

May 17, 2016 · Notwithstanding these comments, we will continue with oxygen delivery within the context of this article in order to remain consistent with common custom and usage. Global oxygen delivery describes the amount of oxygen delivered to the tissues in each minute and is a product of the cardiac output and arterial oxygen content.Author: J-Oc Dunn, MG Mythen, MP Grocott, MP Grocott

(One notable exception when oxygen dissolved in plasma is a major contributor is carbon monoxide poisoning: hemoglobin has 230 times greater affinity for carbon monoxide than oxygen.) Tissue blood flow is equal to cardiac output. For a more complete discussion of this, please see link in “See Also” (right). Oxygen Delivery

This reflects poor O2 delivery resulting from too few RBCs or from RBCs that contain abnormal or too little Hb. ... Carbon monoxide poisoning. ... Transport of oxygen from lungs to body cells and carbon dioxide from tissue cells to lungs.

The presence of carbon monoxide in the blood will result in a profound decline in the capacity of blood to carry oxygen. Thus, although the partial pressure of dissolved oxygen in the blood may be normal, tissues may display severe hypoxia because much of the hemoglobin will be irreversibly bound by carbon monoxide rather than oxygen. Furthermore, because of the cooperative nature of oxygen ...

Carbon monoxide (CO) is an important cause of poisoning morbidity and mortality in many developed countries. The two most common sources of the gas in acute poisonings are smoke from fires and car engine exhaust fumes (in the absence of a catalytic converter).
https://en.wikipedia.org/wiki/Carbon_monoxide_poisoning
The true number of cases of carbon monoxide poisoning is unknown, since many non-lethal exposures go undetected. From the available data, carbon monoxide poisoning is the most common cause of injury and death due to poisoning worldwide. Poisoning is typically more common during the winter months.Deaths: >400 non-fire related a year (US)

Jan 03, 2017 · Carbon monoxide bound to the tissues may prevent oxygen utilization. In some ways, this may be a thornier issue than #1. ... Cardiac output will increase the oxygen delivery to the tissues. RBC transfusion (or exchange transfusion). Anemia is problematic because this will impair both tissue oxygen delivery and tissue CO removal.

Effects of carbon monoxide (CO) delivery by a CO donor or hemoglobin on vascular hypoxia inducible factor 1α and mitochondrial respiration ... function. CO ligated to Hb does not adversely affect mitochondrial function. CO ligated to Hb delivers less oxygen to target tissues than unligated Hb. This work provides new insight for CO therapeutics ...Author: Chad E.N. Reiter, Abdu I. Alayash
